Mariah cuts a rectangle along its diagonal. Two congruent triangles are created. The two angles created by the diagonal have a s

Savatey [412]

X + y = 90 because the 2 angles add up to 90

Now m < x = five times m < y, so x = 5y or y = x/5

so the last choice is the correct one.

Solve for x in the diagram below.

gogolik [260]

Answer:

x = 9

Step-by-step explanation:

The parallel lines divide the sides of the triangle in proportion, that is

$\frac{20-8}{x}$ = $\frac{8}{6}$

$\frac{12}{x}$ = $\frac{8}{6}$ ( cross- multiply )

8x = 72 ( divide both sides by 8 )

x = 9
