15. The measure of the second angle in a triangle is four more than the measure of the first angle
and the measure of the third angle is eight more than twice the measure of the first angle. Find
the measure of each angle.

Step-by-step explanation:

second: 4+x

first:x

third:2x+8

180=4+x+x+2x+8

180=12+4x

168=4x

x=42

42+4=46

2*42+8=92

first angle: 42

second angle:46

third angle:92
