Answer:
A. 24
Step-by-step explanation:
Angles in a triangle add up to equal 180
Thus, 66 + 90 + x = 180
66 + 90 = 156
156 + x = 180
180 - 156 = 24
Hence, x = 24
Note: There is a right angle indicated by the square inside of the triangle. A right angle has a measure of 90 degrees. So Just in case you were wondering that's where the 90 cam from
Answer:
75 degrees
Step-by-step explanation:
1. Find angle J.
The outside angle and angle J are supplementary, which means they add up to 180 degrees.
180 - 130 = 50.
So angle J is 50 degrees.
2. The angles in a triangle add up to 180. Add up angles J and K and subtract that from 180
50 +65 = 105
180- 105 = 75
Answer:
the answer is A
Step-by-step explanation:
So 9 students = 25% (100%-75%=25%)
100 : 25 = 4
4 * 9 =
36 students
