Question

How do you solve this? And what would the answer be?

Answer 1

Answer: 62

from that pic, we could know that angle C = 180 - 116 = 64

and for the angle A:

(2x + 4) + (3x - 13) + 64 = 180

5x + 55 = 180

5x = 125

x = 25

Angle A = 3x - 13 = 3(25) - 13 = 62

So the answer is 62.

Answer 2

from that pic, we could know that angle C = 180 - 116 = 64

and for the angle A:

(2x + 4) + (3x - 13) + 64 = 180

5x + 55 = 180

5x = 125

x = 25

Angle A = 3x - 13 = 3(25) - 13 = 62

So the answer is 62.
