Figure TUVS is a parallelogram. Parallelogram T U V S is shown. Angle U is (4 x + 9) degrees and angle V is (6 x minus 29) degrees. Which angles equal 91°? angles T and V angles S and U angles U and V angles S and T

It’s going to be d. 4x^2-4x-19’

Google it that might work

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
