A gardener is planting two types of trees: Type A is 7 feet tall and grows at a rate of 5 inches per year.
Type B is 6 feet tall and grows at a rate of 8 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
