The tangent of a given circle is perpendicular to the radius a the point called point if tangency. The radius of the circle is perpendicular to the tangent at the point of tangency. This property is especially useful in cases where the radius that connects to the point of tangency forms a part of right angle because the pythagorean theorem and trigonometry apply to right angles.
It will take rita 4.5 days to travel to her destination
Answer:
Step-by-step explanation:
d + q = 32
.10d + .25q = 5.00
d + q = 32
10d + 25q = 500
-10d - 10q = -320
10d + 25q = 500
15q = 180
q= 12 quarters
d + 12 = 32
d = 20 dimes
