Which equation should you use to solve for x?

40°
60°
16x
O 60 + 16x + 40 = 180
O 60 + 40 = 16x
0 60 + 16x = 40
O 60 + 16x + 40 = 90

Answer:

Option: A.

Explanation:

Hey there!

In the given triangle;

60° +16x° + 40° = 180° { Sum of interior angle of a triangle}

100° + 16x= 180°

16x = 180° - 100°


x = (80)/(16)

Therefore, X= 5°.

So, Option A (equation) is used for solving the value of"X".

Hope it helps...
