Answer:
30°
Step-by-step explanation:
It's an equilateral triangle, which means that the angle at the center is 60°. The angle where the tangent line touches the circle is 90°. You have 2 out of 3 angles. Now all you have to do is subtract the two angles from 180°.
180 - 90 - 60 = 30

Answer:
Step-by-step explanation:
-8y = -2x + 16
y = 1/4x - 2
y = 1/4x + 3
Answer: Its width is 6inches.
Step-by-step explanation:
The given information can be used to construct a right angled triangle. Now applying the Pythagoras theorem,
10^2 = W^2 + 8^2
where w represents the width.
100 = w^2 + 64
100 - 64 = w^2
36 = w^2
find the square root of both sides,
6 = w
Therefore, w = 6 inches
Thus the width of the rectangle is 6 inches.
