Question

Can someone please help me on this?

Answer 1

First angle: 27

Second angle: 135

Third angle: 18

Draw a triangle with one obtuse angle and 2 acute angles.

Explanation:

Determine the variables:

first angle: f

second angle: s

third angle: t

Write an equation for the second angle:

s=5f

Write an equation for the third angle:

t=2/3f

Write an equation for the total angle measurements:

s+t+f=180

Substitute them and solve

5f+2/3f+f=180

f=27

5(27)=135=s

2/3(27)=18=t

First angle: 27

Second angle: 135

Third angle: 18
