    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 x degrees
    Angle B is four times as big as x (angle A) so would be 4x degrees
    Angle C is 36 more than angle A, so is x+36 degrees

    Angles in a triangle have to add up to 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.
