Answer:
3
Step-by-step explanation:
first you would solve 2^3. It is 2x2x2 which is 8. Then you do 20-8 which equals 12. Then to finish it off you do 12/4 which is 3
Answer:
138°
Step-by-step explanation:
∠YUV creates arc YV. Circle Z is made up of arc UV (84°) and arc YV. Solve for the measure of arc YV. (A circle equals 360°)
84° + x = 360°
arc YV = 276°
arc YV is formed from a secant and a tangent. Because of this ∠YUV is half of arc YV.
276° ÷ 2 = 138°
∠YUV = 138°
