Question

practice d: (first taught in lesson 51) find y. after you enter your answer press go. y =

Explanation:

Step1: Use the property of trapezoid

In an isosceles trapezoid (the non - parallel sides are equal, as indicated by the tick marks), consecutive angles between the parallel sides are supplementary. That is, \(y + 105=180\).

Step2: Solve for \(y\)

Subtract \(105\) from both sides of the equation \(y + 105=180\). So, \(y=180 - 105\).

Answer:

\(75\)
