Question

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.

Answer 1

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
