Question

lines intersect at a point, forming ∠1 , ∠2 , ∠3 , and ∠4 . ∠1 and ∠2 are supplementary angles. ∠2 and ∠4 are vertical angles. m∠1=90° What is the measure of ∠4 ? Need The Answer ASAP. Thank you guys who do answer.

Answer 1

supplementary angles will always add up to 180. Vertical angles are always opposite to each other. If <1 is 90, then <2 is also 90. since 4 is opposite of that, it will also be <90

hope i was help :)
