1.
1=87 corresponding angle.
2=180-87=93
2.
1=78 corresponding angles
2=78 verticle angles
3.
Set it up as (6x - 11) = 37
37 + 11 =48
6x = 48
x = 8
4.
Take 142 and see that it is supplementary to angle 2 so 180-142 = 38
38 is corresponding to the equation 2(x + 9)
So 2(x + 9) =38
Distributive property
2x + 18 = 38
38-18=20
2x =20
x = 10
Angle 2 is equal to 38 from supplementary to 142
I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct

Inverse Variation
Step-by-step explanation:
We try to represent each number inside the square root as a product of a square and another number.
a) 7√32 - 5√2 + √8
√32 = √(16 *2) = √16 * √2 = 4* √2 = 4√2
√8 = √(4 *2) = √4 * √2 = 2* √2 = 2√2
7√32 - 5√2 + √8 = 7*(4√2) - 5√2 + 2√2 =
= 28√2 - 5√2 + 2√2 Factorize out √2
= (28 - 5 + 2)√2
= 25√2
b) 2√150 - 4√54 + 6√24
√150 = √(25 * 6) = √25 * √6 = 5*√6 = 5√6
√54 = √(9 * 6) = √9 * √6 = 3*√6 = 3√6
√24 = √(4 * 6) = √4 * √6 = 2*√6 = 2√6
2√150 - 4√54 + 6√24 = 2*(5√6) - 4*(3√6) + 6*(2√6)
= 2*5√6 - 4*3√6 + 6*2√6
= 10√6 - 12√6 + 12√6 Factorize √6
= (10 - 12 + 12)√6
= 10√6
