Answer:
x = 10
Explanation:
An angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.
8x - 5 = 1/2(14x + 10)
8x - 5 = 7x + 5
8x - 6x = 5 + 5
x=10°
We have:
the angle of tangency is half of the measure of the arc formed on the same side.
So,
(8x-5)°=½*(14x+10)°
8x-5=7x+5
8x-7x=5+5
