a. Define the variable: (1 point)


b. Find an expression for the first and second angle. (1 point)




c. Write the equation that represents this situation. (2 points)



d. Solve for x. (2 points)



e. Answer in complete sentence: (1 point)
PLZZ I need help I just don't understand this question ill fan

Answer 1

Let x be the number.

Let <1 and <2 be the angles

m<1 = 2x + 20

m<2 = 4x -68

If the two angles are congruent, then m<1 = m<2.

Solve for x: 2x + 20 = 4x - 68

Post what you get, okay?

Answer 2

ok

Answer 3

@directrix I really cant figure it out

Answer 4

@goprogo501 this is the one

Answer 5

You can do this:

2x + 20 = 4x - 68 Solve for x

2x - 4x = -68 - 20

?

Answer 6

oh I didn't know I had to do that

Answer 7

What is 2x - 4x =

Answer 8

-2x

Answer 9

What is -68 - 20 =

Answer 10

-88

Answer 11

2x + 20 = 4x - 68
2x - 4x = -68 - 20
-2x = -88
x = ?

Answer 12

-44

Answer 13

-88 divided by -2 = + 44

Answer 14

x = 44

Answer 15
