Answer: B = 18 degrees
C = 48 degrees
Step-by-step explanation:
Complimentary angles are angles whose sum is 90 degrees.
Angle A, angle B, and angle C are complementary angles. This means that
A + B + C = 90- - - - - - - - - - - - -1
The measure of angle C is twice the measure of angle A. If the measure of angle A is 24 degrees, it means that the measure of angle C would be 2 × 24 = 48 degrees.
Substituting A = 24 and C = 48 into equation 1, it becomes
24 + B + 48 = 90
72 + B = 90
B = 90 - 72
B = 18 degrees
Answer:
x=1
Step-by-step explanation:
You can divide by 3 on both sides instead of distributing.
x+2=9÷3
x+2=3
x=3-2
x=1
Answer:
The interest rate is 10%.
Step-by-step explanation:
Interest = principal * rate * time
time is always in years. 6 month = 0.5 year
1.) 165 = 3300 * r * 0.5
2.) multiply 0.5 and 3300
165 = 1650r
3.) divde 1650 to each side
0.1 = r
0.1 = 10%
Answer:
measure of each angle of a regular octagon=360/8=45°
at the point, 60°+x+45=360°
x=255°
