Answer:
y = 3.4
Step-by-step explanation:
Given 2 secants and a tangent drawn to the circle from an external point then
The square of the measure of the tangent is equal to the product of the external part of the secant to the entire secant.
Using the secant with measure y + 11, then
y(y + 11) = 7²
y² + 11y = 49 ( subtract 49 from both sides )
y² + 11y - 49 = 0 ← in standard form
with a = 1, b = 11 and c = - 49
Using the quadratic formula to solve for y
y = ( - 11 ± ) / 2
= ( - 11 ± ) / 2
= ( - 11 ± ) / 2
y = or y =
y = - 14.4 or y = 3.4
However y > 0 ⇒ y = 3.4 ( nearest tenth )
Plug in the numbers wherever these letter are. Ex: 10x+5y. You would do 10x12=120 and 5x20=100. Add these two numbers to get 220. Hope this helps:)
