What is the value of x?<br> What is the measure of angle QOR?<br> What is the measure of angle ROS?
Veseljchak [2.6K]

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

(x + 5) + (2x + 7)  = 90\\ 2x + x + 5 + 7  = 90 \\ 3x + 12  = 90 \\ 3x  = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26

Sub x in

(x + 5) \\ 26 + 5 = 31

and

(2 \times 26 + 7) \\  = 52 + 7 \\  = 59

Use the Distributive Property to solve the equation. 2x−4​(x−3​)=−8+5x-8
andrew11 [14]

Answer:

x = 4

Step-by-step explanation:

Distributive Property: a(b + c) = (a*b) + (a*c)

           2x - 4(x - 3) = -8 + 5x - 8

2x + x * (-4) - 3*(-4) = -8 + 5x - 8

          2x - 4x + 12  = -8 + 5x - 8    

   2x -  4x - 5x + 12 = -8 - 8

               -7x  + 12  = -16

                       -7x  = -16  -12

                      -7x   = -28

                          x = -28/-7

x = 4
