Angle A, angle B, and angle C are complementary angles. The measure of angle A is 24 degrees. The measure of angle B is unknown,
tester [92]

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

The pair of variables x=5, y=7 is the solution to the equation ax–2y=1. Find the coefficient a.
Wewaii [24]

Answer:

a=3

Step-by-step explanation:

This should be very simple, just substitute xy and y for 5 and 7 respectively, so 5a-2*7=1, or 5a-14=1, or 5a=15, if we divide both sides by 5, we get a=3
