Nina would have ran 5 miles because if clara ran 10 and thats twice as far as nina 10 divided by 2 is 5
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:
0.2
Step-by-step explanation:
Simplify the right hand side:

Expand the left hand side:

Subtract 2x from both sides:

Divide both sides by 4:
