QUESTION POSTED AT 19/02/2020 - 12:21 PM

There exists the same question with the figure as shown in the attachment.

The given are:

g = 40 degrees

k = 45 degrees

Ask:

angle of " l "

So this is how to solve this:

Step 1:

Since CEF is an equilateral triangle, then each has 60 degrees.

i is equal to l because they are opposite angles

Step 2:

angle l is inside CEF, then the value of angle l is 60

The given are:

g = 40 degrees

k = 45 degrees

Ask:

angle of " l "

So this is how to solve this:

Step 1:

Since CEF is an equilateral triangle, then each has 60 degrees.

i is equal to l because they are opposite angles

Step 2:

angle l is inside CEF, then the value of angle l is 60

The answer is b) Mia is closer because her distance to the chest is opposite the smaller angle.

In the relationship of triangle sides and its angles, the shortest side will always be opposite to the smallest interior angle. Furthermore, the largest side will always be opposite to the largest interior angle. Since Mia's distance to the treasure chest is opposite to the smaller angle 65°, then she is much closer to the chest.

(1) To find the angle between v and positive x-axis, we first determine the angle formed by v and the negative x-axis. Since v = (-7,8), its vertical measure y is 8 units and horizontal measure x is 7 units.

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

arctan(8/7) = 48.81°

Solving for angle between v and positive x-axis:

180° - 48.81° = 131.19°

(2) v1 x v2=|v1||v2|cosθ

Calculating for the dot product of the vector:

v1 x v2 = -7*1 + 8*0 = -7

Calculating vector magnitude:

|v1| = √(-7²+8²) = √113

|v2| = √(1²+0²) =1

cosθ = (v1 x v2) /|v1||v2| = -7/(√113 *1) = -0.659

The area is 38 because whenever you have to find the area in an equation you always add up the total sides. The shape is a rectangle and the only numbers they give is 6 and 13 obviously the sides are equal so the opposite side of 13 is 13 and the opposite side of 6 is 6 because they're both a certain length. In total you add up all the sides 13 plus 13 is 26, 6 plus 6 is 12 , 26 plus 12 is 38

The perimeter is 78 because they only give you two number so whenever you do a perimeter in an equation you always have to remember to multiply. 13 multiplied by 6 is 78. Hope this helped ( :

First you have to find out how much one pen costs. To do that, all you have to do is divide $11.77 by 11. So,

$11.77/11=$1.07

Then it's just trial and error from there in till you find one that matches. So,

A. 4*$1.07= $4.28( This one is wrong )

B. 5*$1.07= $5.35( This one is wrong )

C. 6*1.07= $6.42 ( !!This one is RIGHT!! )

D. 7*1.07= $7.49 ( This one is wrong )

$11.77/11=$1.07

Then it's just trial and error from there in till you find one that matches. So,

Well a circle is 360 degrees and the angle turns 125 of that. a fraction can be considered a ratio of a part of the whole vs the whole and can be written as:

part/whole

So the part is 125 and the whole is 360 so

125/360

This can be reduced by 5

25/72

That is your answer

QUESTION POSTED AT 29/03/2020 - 06:28 PM

**Answer:**

Option C

**Step-by-step explanation:**

A and B are said to be independent of

P(A intersection B) = P(A)*P(B).

Or if drawing is done with replacement, etc.

A) P(drawing a king) = 4/52 = 1/13

IF we replace again drawing a kind is the same 1/13

Hence independent

B) Coin flipping each toss is obviously independent of the other as prob of getting tail in a fair coin is 1/2 irrespective of the previous outcomes

C) Without replacement is not independent

Since first prob = 4/52 and second would be 3/51 not the same as before

D) Rolling a die is independent as getting a 2 in any throw is always the same.

C is answer

**Answer with explanation:**

Two Triangles are Congruent by following Geometrical Axioms

1. SAS

2.SSS

3. AAS

4. ASA

1. In Δ DEF and Δ P QR

PQ=DE

∠DEF=∠PQR→→Each being 90°

EF=QR

Δ DEF ≅ Δ P QR→→[SAS Congruency]

2. As in Image 2, only one angle is common

we can't say that triangles are congruent.

3. In ΔT UV and Δ W X Y

WX=TU

UV=XY

TV=WY

∠TUV=∠WXY

∠UTV=∠XWY

ΔT UV ≅ΔW X Y→→[By SAS or AAS or SSS]

4.In ΔABC and ΔFGH

∠A=∠F=83°

we can't say that triangles are congruent,as neither the other two angles nor the other two sides are equal.

5. None of the sides nor of the angles are equal .So the triangles are not congruent.

**→→So, Image 1, Image 3, are congruent Polygons. **

so

divide boths ies by 180

5/3=n-2

add 2 to both sides (2=6/3)

11/3=n

you can't have 11/3 number of sides, yo have to have a whole number of sides

so no, that is impossible, will never happen
