Answer:
56 degrees.
Step-by-step explanation:
We need the measure of < g.
The triangle formed by the 2 tangents and the chord is isosceles, because 2 tangents from a point outside a circle are of equal length (by the Two Tangents theorem).
Also one of the base angles are equal to 62 degrees ( by The Tangent Chord theorem). In fact both base angles are 62 degrees because the triangles an isosceles.
So measure of angle g = 180 - 2(62)
= 56 degrees.
2^2+b^2=12^2
4+b^2=144
144-4=140
√140 = √b
11.83 = b
If X = 23, the. 23 - 6 = 17.
7% of 79.99 is (rounded) 5.60 so the total cost would be $85.59
