Answer:
c 15
Step-by-step explanation:
Tangent AB is tangent to circle D at point A. The angle made by a tangent to a circle and a radius of the circle at the point of tangency is a right angle. That means that angle is a right angle, and triangle ABD is a right triangle.
We can use the Pythagoren theorem.
a^2 + b^2 = c^2
x^2 + 20^2 = (x + 10)^2
x^2 + 400 = (x + 10)(x + 10)
x^2 + 400 = x^2 + 10x + 10x + 100
400 = 20x + 100
20x = 300
x = 15
Answer:330 degrees

X=(3+1+2)x h. X=the total cost
H=how many kids on the math team
<em>Hi there,</em>
Principle Amount = $14000
Interest for 1 year = 4% x 14000 = 0.04 x 14000 = $560
Interest for 2 years = 560 x 2 = $1120
Total amount at the end of the period = $14000 + $1120 = $15120
Answer: $15120
