Will mark brainliest if ! plz i don’t understand at all & missed a week of school because i was sick.

find m

23 degrees

Step-by-step explanation:

A straight line = 180 degrees, and there's a 90 degree angle on the left side, so (2x+14) + (x+7) = 90.

Then, just solve the equation.

3x + 21 = 90

3x = 69

x = 23

Therefore, m = 23 degrees

23 degrees

Step-by-step explanation:

A straight line = 180 degrees, and there's a 90 degree angle on the left side, so (2x+14) + (x+7) = 90.

Then, just solve the equation.

3x + 21 = 90

3x = 69

x = 23

Therefore, m = 23 degrees

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
