It looks floppy but you said you need this fast so yeah
The anwser would be -15
3 x (-5) = -15
For this case, the first thing you should know is that by definition, the vertical angles are congruent.
We have then:
∠1 and ∠2 are vertical angles.
Therefore, by definition:
∠1 = ∠2
On the other hand we have:
∠2 has a measure of 31 °.
Thus:
∠1 = ∠2 = 31 °
Answer:
the measure of ∠1 is:
∠1 = 31 °
ANSWER: 9/91
EXPLANATION:
4x+2/39=5x-1/21
-x+2/39=-1/21
-x=-9/91
x=9/91
Well make 3.5 into a whole number then add it together
