Angles
i. Angles A, B, and C are the angles in a triangle. Angle B is 4 times as big as angle A, and angle C is 36 degrees more than angle A. Find the measure of angle A in degrees.
ii. The measure of the larger of the acute angles in a right triangle is 3 degrees less than 5 times the measure of the smaller. Find the measure of the smaller angle.

I agree with Wilmer.

But here's how I would start:

i. Let angle A be \$\displaystyle x\$ degrees
Angle B is four times as big as \$\displaystyle x\$ (angle A) so would be \$\displaystyle 4x\$ degrees
Angle C is 36 more than angle A, so is \$\displaystyle x+36\$ degrees

Angles in a triangle have to add up to \$\displaystyle 180\$.

So Angle A + Angle B + Angle C = 180

So how would you finish?

ii. Follow the same principle as i. but this time, a diagram would probably make things clearer.
