Complete the following proof: Given:
<1 and <3 are vertical angles
<2 and <4 are vertical angles
<1 and <2 are supplementary angles

Prove:
<3 and <4 are supplementary angles

Which expression is equivalent to 2^4y^3

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

This is my question~~ ( r ^ 4 - 2r ^ 3 - 23 r ^ 2 - 4r - 32)÷(r+4) ~~ i must use long division to solve it : / i was wondering if anyone world like to solve it. and if so, share step-by-step explanations! you! ❤
