9. Find the exact value of Tan(225). First use the Reference Angle Theorem. Then use values obtained from the 45, 45, 90 degrees Special Right
Triangle.

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Average acceleration: i have no idea how to do this.

Which expression converts 45 degree to radians
