Answer:
∠C=90°
∠A=67°
∠B=23°
Step-by-step explanation:
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°
Answer: You determine the coefficient by looking to see if there is a number in front of a variable. If there is a number in front of the variable, then that is the coefficient. The coefficient is the number, and the variable is the letter.

Answer: 123
Step-by-step explanation:
The answer is 9:50. This is because 45 minus 35= 10. You subtract the leftover ten from 10:00 and get 9:50. Hope this helps!
Answer:
Step-by-step explanation:
Set B = 60 elements
Set A = x elements
A∩B = 12
A∪B = 82
x = (82+12 - 60) = 34 elements
