Math Humor Q: Why was the chord upset with the tangent after their race? A: They came in secant!
Example 1 Find each measure. mFH 65˚ 116˚ ½(130) 360 -244
Example 2 Find each angle measure. mRNM 22˚ 1/2 [360 – (225 +91)]
Example 3 Find the value of x. 33˚ 25 = 1/2 [83 – x] 50 = 83 –x x = 33
Example 4 In the company logo shown, = 108°, and = 12°. What is mFKH? 48˚ 1/2 [108 – 12] x = 48
Example 5 Find mLP
