If road A and C are parallel and road D is 2000 feet, Road c has a section 650 feet long how long is the rest of it

I think,
Road C equals 650, because road A is parallel it must equal the same.
So, 650 + 650 = 1,300
We already know that Road D equals 2,000, add it all up.
1,300 + 2,000 = 3,300
Hope this helped :)

QUESTION POSTED AT 28/02/2020 - 07:01 AM

I need to know how the solve the answers below

S is given as 58 degrees.

There are 180 degrees in a triangle. Using this you know that S + T + TUS = 180

T is given as 5x + 10

TUS can be defined as TUS + AUT = 180, or TUS = 180 - AUT

AUT is given as 11x + 2

Plug everything into the first equation to give you 58 + (5x + 10) + (180 - (11x + 2)) = 180

Solve for x, and be careful with the negative in front of (11x+2)

58 + 10 + 180 - 2 + 5x - 11x = 180

-6x = -66
x = 11

Plug x back into the equations for AUT and T to get your final answers.

AUT = 11(11) + 2 = 123 degrees
S = 58 degrees
T = 5(11) + 10 = 65 degrees
TUS = 180 - AUT = 180 - 123 = 57 degrees

You can check your answer by making sure
S + T + TUS = 180, which it does.

The greater of two numbers is one less than eight times the smaller . Their sum equals 98

B>a

b=8a-1

and we are told that 98=a+b so a=98-b, using this value for a in the equation above gives you:

b=8(98-b)-1

b=784-8b-1

b=783-8b

9b=783

b=87, and since a+b=98, a=11

so a and b are 11 and 87

You use right triangle trig here. You have the angle of 71 degrees, which is the base angle that is NOT the right angle.  The length of the beam serves as our hypotenuse. The sin ratio calls for SOH...sin = side opposite over hypotenuse, right? So set it like this: sin 71 = x / 24, where x is the leg that is NOT the base. Make sure your calculator is in degree mode and multiply both sides by 24 to get an equation that looks like this: 24 sin 71 = x. Do the multiplication to get that x = 22.69 ft
