Write and solve an equation to determine the value of X of a right triangle if one of the angles measure (2.5x) and the other angle measures (3.5x)

Question

I need help with sum of angles in a triangle, please help homework is due tomorrow 

Answer 1

the sum of the three angles of a triangle equals 180 degrees

in a right triangle, one of the angles is 90 degrees

2.5x+3.5x+90=180

6x+90=180

6x=180-90

6x=90

x=90/6

x=15 answer

2.5x=2.5*15=37.5º

3.5x=3.5*15=52.5º
