Answer:
m∠P = m∠Q = m∠R = 60º
Step-by-step explanation:
Because each of the sides are congruent, the angles are congruent. A triangle must add up to 180º, so when you divide 180 by 3, you get 60. Therefore, each angle is 60º.
Answer:
(x-3) (x+10)
Step-by-step explanation:
Remember SOH CAH TOA
we want the angle between the ground and the hypotenuse
which gives us

or 45.08 degrees
