If two lines are crossed by another line that is called the transversal, the corresponding angles those in matching corners. In this problem, we have two parallel lines:

In this way, x° and 76° are corresponding, therefore:
(x)° = 76°
∴ x = 76
Answer:
XY is a tangent
Step-by-step explanation:
Given



Required
Is XY a tangent?
XY is a tangent if:

Because XY should make a right angle at point X with the circle
Where

So, we have:




This gives:



<em>Yes, XY is a tangent</em>
Answer:
When sides are doubled, the area of new triangle will always be 4 times the original, the change in area will be 3 times. Hence the % change will always be 300% irrespective of the type of triangle.
Step-by-step explanation:
The answer is none because the square cannot be rotated into a cone or a cylinder. The square would need some sort of a circle to be made into those.
Multiply the two values together to get 45 * 3/5 = 135/5 = 27
