x≈3.4

Step-by-step explanation:

Since the triangle in the box is on a scale of 4 to the top left triangle sketch, you need to multiply 0.84 by 4 which will equal x.

0.84×4=x

x=3.36

x≈3.4

If you're roudning, 3.4

if not, 3.3

Step-by-step explanation:

Since the two triangles are similar, we can use proportions

1/0.84 = 4/x

x = 4 * 0.84

x = 3.36

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

angle addition postulate

2x=56
