Answer:
They tie the race
Step-by-step explanation:
Big Kangaroo: 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4 = 12 hops
Small Kangaroo: 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2, 2 2 = 12 hops
Each hop is separated by a comma
-189
If you continue the pattern by multiplying the term by -3, you will eventually get -189 as the 6th term
∠C=90°
∠A=67°
∠B=23°
For angle C:
Thales' Theorem states that an angle inscribed across a circle's diameter is always a right angle.
Therefore, since AB is the diameter(hypotenuse) then angle C is the right angle. (90°)
For Angle A:
The measure of arc BC= 134 degrees. We can just use a formula for an inscribed triangle. ∠A = 1/2 (mBC)
∠A= (1/2)134
∠A= 77°
For angle B:
All triangle angles all add up to 180. We can just subtract angles A and C from 180°:
∠B = 180-(90+67)
∠B = 23°
