Can someone please tell me the answer to this problem
−9 =3(m − 5)−m

m = 7

Step-by-step explanation:

distrubute 3 into the parenthesis so

-9 =  3m-5-m

combine like terms (m) -> 3m-m= 2m

9 = 2m - 5

+5         +5

14 = 2m

*divide by 2*

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
