-6x^4-7x^2+5x-10. hope this helps ! :)
The answer would be b.100 because its clearly not a right triangle
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 °
The first question answer is 21*10^7
The second question answer is 5*10^2
