Please help

The second angle of a triangle is 104 more than the first angle. The third angle is two times the first. Find
the three angles.

First angle:
Second angle:
Third angle:

Answer 1

First let’s set it up as
First angle=X
Second angle=Y
Third angle=Z

Let’s Define our Y & Z

Y=x+104
Z =2x

Make your equation knowing the all 3 angles of any triangle = 360°

x+y+z=360

Plug in your previous Y and Z values

x+(x+104)+(2x)=360

Solve for X

4x+104=360

4x=256

x=64

You now have your X value, take that number and plug it back in to your original Y and Z values

First Angle: 64
Second Angle: 168
Third Angle: 128
