Answer:
x = 130°
Step-by-step explanation:
At the points of Tangency, A and B, the angle formed are equal to 90° based on the tangent theorem.
Therefore, m<A and m<B both have a degree measure of 90° each.
Thus, the sum of the interior angles of quadrilateral AOBC = 360° (sum of interior angles of a quadrilateral).
Therefore:
x + m<A + m<B + m<C = 360°
x + 90 + 90 + 50 = 360 (substitution)
x + 230 = 360
x = 360 - 230 (subtraction property of equality)
x = 130°
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13

Step-by-step explanation:
Recall: SOHCAHTOA
Thus,
Reference angle = 28°
Adjacent = 15
Hypotenuse = 17
Plug in the values
Answer:
The cost would be $81.09
Step-by-step explanation:
In order to find the amount Chris will spend, start with the equation and input 100 for every x that you see.
c=0.765x +0.06(.765x)
c=0.765(100) +0.06(.765[100])
c = 76.50 + 0.06*(76.50)
c = 76.50 + 4.59
c = 81.09
