Answer:
Step-by-step explanation:
a). Equation: m∠K + 40° + 60° = 180°
[Since, these angles are located at a point of a straight line so they are supplementary angles]
b). m∠K = 180° - 100°
m∠K = 80°
c). Equation: m∠M + m∠K = 180°
[Since, ∠M and ∠K are the supplementary angles]
d). m∠M + 80° = 180°
m∠M = 180 - 80
= 100°

Answer:
446.75 y^2
Step-by-step explanation:
First, Kelly found the area of a circle, not half a circle, which is on top of the figure. She also shouldn't have subtracted the area of the circle by the airea of the base, as she is trying to find the area of the ENTIRE figure.
.5 TIMES pi times 9^2 = 122.75
the second part, calculating the square base is correct..
122.75+324 = 446.75 y^2
216
