I'm just going to take a chance and say 1.A, and 2.D.
Answer:
11
Step-by-step explanation:
The distance between -7 and 4 is 11. -6 stays the same. So we just either move up or down.
Problem 16)
We use ASA (angle side angle) to show the two triangles are congruent. Why ASA instead of AAS? Because the single pair of sides are between the two angles.
--------------------------------------------
Problem 18)
Similar to problem 16, we'll have two pairs of congruent angles, and a pair of congruent sides. However, the sides are NOT between the two angles. So that means we use AAS in this case.
It shouldn't add up to 180 degrees, you're looking for the length of the sides not the degree of the angle. Because it's an equilateral triangle, all sides are the same, so you can just set them equal to each other. D=5
Add 21/2 + 31/5 + 11/3 = 20 11/30
