Complement of an alngle means what you need to add to it to make 90 degrees
comlement of angle x is y such that x+y=90
so if complement of angle x is 25, that means the angle x is found by
x+25=90
minus 25 both sides
x=65 degrees
the angle measures 65 degree
Y equals 3/2x plus 10 (4,12)
4 is x and 12 is y
y=3/2x+10
12=3/2(4)+10
12=3/8+10
12=0.375+10
12=10.375
10 is not equivalent/equal to 10.375
Remark
Are you sure you don't mean that (x - 7) is squared? The way you have written it indicates that it is squared. I'll treat it that way and you can leave a not if I am wrong.
Solution
(x - 7)^2 - 25 = 0 Add 25 to both sides
(x - 7)^2 - 25 + 25 = 25 Combine the left
(x - 7)^2 = 25 Take the square root of both sides.
sqrt(x - 7)^2 = sqrt(25)
x - 7 = +/- 5 Add 7 to both sides
x = 7 +/- 5
=========
x1 = 7 + 5
x1 = 12
x2 = 7 - 5
x2 = 2
Smallest x = 2
Largest x = 12
