Answer:

Actually, i believe it is A, because first, you need to get rid of the -9, so you need to add. That would leave x = 24 which would be the correct answer.

Step-by-step explanation:

It may not look like a negative 9, but its part of subtraction. Its just how it works.

Find the value of x. Show all work.

Mashutka [201]

Answer:

x = -8°

Step-by-step explanation:

Angle 2

Since the triangle is isosceles, Angle 2 is the same as the missing angle

So angle 2 would be:

180 - 34 = 2(angle 2)

So 146 = 2(x + 81)

146 = 2x + 162

146 - 2x = 162

-2x = 16

x = -8

Check

146 = 2(-8+81)

146 = 2(73)

146 = 146

Correct!

If my answer is incorrect, pls correct me!
