Answer:

First angle: 27

Second angle: 135

Third angle: 18

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

Step-by-step explanation:

<u>Determine the variables</u>:

first angle: f

second angle: s

third angle: t

<u>Write an equation for the second angle:</u>

s=5f

<u>Write an equation for the third angle:</u>

t=2/3f

<u>Write an equation for the total angle measurements:</u>

s+t+f=180

<u>Substitute them and solve</u>

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
