Answer:
C. 75°
Step-by-step explanation:
We have been given a circle and we are asked to find the measure of angle AEC.
We will use Intersecting chords theorem to find the measure of angle AEC, which states that measure of angle formed inside a circle by two intersecting chords is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.
We can see that measure of arc AC is 110 degrees and measure of its vertical arc BD is 40 degrees.
![m\angle AEC=\frac{110^o+40^o}{2}](https://tex.z-dn.net/?f=m%5Cangle%20AEC%3D%5Cfrac%7B110%5Eo%2B40%5Eo%7D%7B2%7D)
![m\angle AEC=\frac{150^o}{2}](https://tex.z-dn.net/?f=m%5Cangle%20AEC%3D%5Cfrac%7B150%5Eo%7D%7B2%7D)
![m\angle AEC=75^o](https://tex.z-dn.net/?f=m%5Cangle%20AEC%3D75%5Eo)
Therefore, measure of angle AEC is 75 degrees and option C is the correct choice.
Answer:
True
Step-by-step explanation:
The variable overhead rate variance refers to the difference in two variables.
The Variables are
1. The actual variable manufacturing overhead
2. The expected variable overhead given the number of hours worked
Labor rate variance is evaluated by
AH(AR - SR)
AH = actual hours
AR = actual rate
SR = standard rate.
The variable overhead rate variance is also calculated the same way except that it replaces the direct labor rates with variable overhead rates
L = rc
= 26.9 * 9*3.14 / 5
= 152.04 to nearest 1/100
