Question

Find x two secant lines
Anyone know the formula?

Answer 1

x = 26°

Explanation:

A secant- secant angle is an angle whose vertex is outside the circle and whose sides are 2 secants of the circle. It's measure is

x = 0.5(66 - 14)° = 0.5 × 52° = 26°

Answer 2

26

Explanation:

The formula is a half the positive difference of the measurements of the intercepted arcs.

That is you do .5(66-14) here.

I'm going to distribute first and instead of find the difference first.

.5(66)-.5(14)

33- 7

26

Or.... you could do the difference first which gives us .5(66-14)=.5(52)=26.

So that angle is 26 degrees.
