Hello,
Let x represent the first angle and the second angle will be 3x and the third will be x+75. We know every triangle has 180 degrees, right? We can set up the following equation:
x+3x+x+75=180 Combine like terms to get:
5x+75=180 Subtract 75 from both sides to get:
5x=105 Divide each side by 5 to get:
x=21 degrees for the first angle.
Now you can figure out the other two angles.
Make sense?
