The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measu
LenaWriter [7]

Answer:

140° and 50°

Step-by-step explanation:

The supplement of the angle (180 - x)

The complement of the angle = (90 - x)

(180 -x) = 4(90-x) - 60

180 - x = 360 -4x - 60

180 -x  = 300 - 4x

180 - x + 4x = 300

 180 + 3x = 300

     3x = 120

      x = 40

   

The supplement (180 - x) =  180 - 40 = 140°

The complement (90 - x) =  90 - 40 = 50°

Find the value of x.
ruslelena [56]

Answer:

4

Step-by-step explanation:

(10 - x ) / x = 3/2                Cross Multiply

2*(10 - x) = 3x                    Remove the brackets

20 - 2x = 3x                       Add 2x to both sides

20 = 3x + 2x

5x = 20                              Divide both sides by 5

x = 20/5

x = 4
