Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = -22
i would pick number C) since i think it would be the correct answer
Answer:
165 cards left
Step-by-step explanation:
x + 221 = 386
-221 from both sides
x = 165

The angle supplementary to x and 3x are equal.
Supplementary angles = 180
Solution
x + 3x = 180
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
The angle supplementary to x is 3x
3x = 3*45
3x = 135
This angle is vertically opposite y. Vertically opposite angles are equal. So y = 135
Answer
x = 45
y = 135
