The measure of an angle is 12° less than twice the measure of its supplement. what is the measure of the angle?
64°
34°
28°
116°

The measurement of the required angle = 116°

Step-by-step explanation:

Let the measure of its supplement = x

The measurement of the required angle = 2x - 12

x + 2x -12 = 180

3x - 12 = 180

3x = 180 + 12

3x = 192

x = 192/3

x = 64°

The measurement of the required angle = 2 * 64 - 12 = 128 - 12 = 116°

answer: add the !

step-by-step explanation: then we will answer

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
