Answer:
∠ 1 = ∠ 3 = 33°
Step-by-step explanation:
∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus
∠ 3 + ∠ 6 = 180° , that is
∠ 3 + 147° = 180° ( subtract 147° from both sides )
∠ 3 = 33°
∠ 1 and ∠ 3 are vertical angles and congruent, thus
∠ 1 = ∠ 3 = 33°

He needs 92 on his last test.
Step-by-step explanation:
Mean score:
The mean is the sum of all scores divided by the number of tests.
In this question:
Scores of 85, 89, 85, 89 and x(the last one).
5 tests.
We want a mean of 88. So we find x for a mean of 88.
He needs 92 on his last test.
