Answer:

Step-by-step explanation:

8.  The angles are equal, so:

(2x+2) = (3x - 63)

-x = -61

x = 61

Angle (2x+2) is 124°

Angle (3x-63) is 120°

9. The sum of all angles in a triangle is 180°.

The sum of the two unknown angles is 90° [180° - 90° from the right angle°]

(8x+2) + (9x+3) = 90°

17x + 5 = 90°

17x = 85°

x = 5

The two angles are:

(8x+2)  =  42°

(9x+3)  =  48°
