second angle of triangle is 3x the size of 1st. 3rd angle is30% more than the 1st. Find the measure of each?

that should say find the measure of each angle. i ran the max character limit.math homework.

A triangle's angles must equal 90 degrees: A + B + C = 180.

Then relate the given data to the previous equation in terms of x, x being the first angle:
x + 3x + (.3x + x) = 180

Simplify:
5.3x = 180
x = 90/5.3 = (approximately) 33.9622

x is the first angle. Plug it in to find the other two angles, but do them separately:

The first angle:
x = (33.9622) = (approximately) 33.9622

The second angle, three times the first:
3x = 3(33.9622) = (approximately) 101.8867

The third angle, 30% bigger than the first:
(.3x + x) = (.3(33.9622) + (33.9622)) = (approximately) 44.1508
