Question

For ΔABC, the measure in degrees of angles A, B, and C are 60, 55, and x + 20 respectively. What is the value of x?

Answer 1

Ok x = 45 because 180-60-55-20 = 45

Answer 2

Explanation:

All sides of a triangle equel 180 degrees, so 180-60-55=115. 180-115 is 65. 65-20-45. Hope this works!
