Find the measure of angle y. a. 115° b. 65° c. 43° d. 22°

The answer is B. 65

Step-by-step explanation:

add 43 and 22, then subtract that by 180 and that will give you 115. Then subtract 180 and 115 and the answer is 65.

According to the property of the triangle, the sum of the two interior angles of a triangle is equal to the opposite exterior angle of that triangle.

Now here,

x is the exterior angle to the triangle and the opposite interior angles to x are 43° and 22°.

Therefore,

x = 43° + 22°

x = 65°

=> Option B (65°) is the correct answer.

5/12, or 5: 12
