Answer:
75°
Step-by-step explanation:
Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°
All we need to do is simply subtract 15° from 90° to find m∠ATB:
90 - 15 = 75°
The line from the center of the circle to the outside is called the radius
Answer:
The sides are increased by a percentage of 25%
Step-by-step explanation:
Let
x -----> the length side of the original square
y ----> the length side of the increased square
we have



the increase is calculated by subtracting x from y
so

Remember that

therefore
The sides are increased by a percentage of 25%
