Answer:
Y = 90
X = 52
Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
The answer is C. 20. Hope this helps!
Answer:
X=30
Step-by-step explanation:
The whole polygon is 360 degrees so:
360-28-40-120-142=X, which is 30
Explanation:
If 
then taking the reciprocal gives
If a function is undefined, this usually means that the
value is 1 / 0.
Since tan theta is the reciprocal of cot theta.
Therefore:
cot theta = 1 / 0 = 1 / tan theta
Taking the right side:
1 / 0 = 1 / tan theta
Rearranging so that tan theta is in the numerator:
tan theta = 0
