Can someone please help me on this?

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:
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
