Question

HELP ME PLEASE :(

The measures of the angles of a triangle are 2x, 3x, and 4x.

What is the degree measure of the largest angle of the triangle?

A.) 20°

B.) 60°

C.) 80°

D.)100°

Answer 1

the angles of a triangle add up to 180 degrees

so your problem is :
2x + 3x + 4x = 180
9x = 180
x = 20

2x = 2(20) = 40 degrees
3x = 3(20) = 60 degrees
4x = 4(20) = 80 degrees

40 + 60 + 80 = 180

so 4x (the largest angle) would be 4(20) = 80 degrees
