Answer:
14. B 9, Isosceles
15. Corresponding angles; alternate interior angles; verticle angles
Step-by-step explanation:
Question 14 explanation -
Because two of the triangle's angles are congruent, this triangle classifies as an Isosceles Triangle. Therefore, we know that sides AB and AC must be congruent. This makes it easy to solve for x...just set both side lengths equal to each other and solve.
mAB = mAC
16 = x + 7
16 - 7 = x + 7 - 7
9 = x
x = 9
Answer:
Because 4 is a perfect square
Step-by-step explanation:
When simplifying a radical, you have to look for perfect squares. 4 is a perfect square but x is not. Variables are only perfect squares if they have even numbered exponents so the x has to stay in the radical.
