If you can please help me on 6,7,8 that would be amazing thank you!

Answer:
Step-by-step explanation:
6. Complementary angles add up to 90 degrees
m<S is 52
90-52= 38
m<R is 38
38=3x+2
-2
3x=36
x=12
7.
Lines are always equal to 180
(5x+1)+(12x-8)=180
17x-7=180
+7
17x=187
x=11
8.
These angles are equal to each other '
79= 4x+15
-15
64=4x
x=16
Hope this Helps!
