In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 88° mo

Alex73 [517]

Answer:

Step-by-step explanation:

The measure of the second angle = n

The measure of the first angle = 2*n

The measure of the third angle = n + 88

==================

n + 2n + n + 88 = 180

4n + 88 = 180

4n = 180 - 88

4n = 92

n = 92/4

n = 23

============

second angle = 23

First angle = 2*23= 46

Third angle = 23 +88 = 111

The total is 180
