The diagram shows the arcs used to construct H], given GI . I
If mZHKI = (7x + 6). GI = 15, and KI = (2y - 3), what are the values of x and y?
А
x = 12
y = 9
B
X = 10.5
y = 5.25
С
x = 12
y = 5.25
D
X = 10.5
y = 9

step-by-step explanation:

should you really be posting this isn't math boi.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

is there any photos or whatever?

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
