Question

Solve for the missing side. Round to the nearest tenth.

Answer 1

Answer:

? = 7.2

Step-by-step explanation:

Remark

Is that a misshapen circle or is it an ellipse? I'm going to assume it is a circle, but if I am wrong, leave a comment. A tangent will meet a diameter's end at right angles which allows you to use the Pythagorean theorem.

Formula

a^2 + b^2 = c^2

Givens

c = 12

a = 9.6

b = ?

Solution

c^2 - a^2 = b^2

144 - 92.16 = b^2

b^2 = 51.84                          Take the square root of both sides

sqrt(b^2) = sqrt(51.84)

b = 7.2
