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

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!

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
