Question

Can someone tell me what the answer is??

Answer 1

Hey! Your answer should be B. 7

Explanation:

Congruent triangles mean that two angles equal the same amount. Therefore <2 should equal 43°, but plugging 43 into the equation provided, you're left with 43= 5x+8.

Subtract both sides by 8 and you're left with 35= 5x.

To get X alone, you'd divide both sides by 5, leaving you with 7 = x. Therefore, the answer is B. 7

Answer 2

B

Explanation:

This is an isosceles triangle. So, m∠2 = 43°

5x+ 8 = 43

Subtract 8 from both sides

5x = 43 - 8

5x = 35

Divide both sides by 5

x = 35/5

x = 7
