Answer: B, D
Step-by-step explanation:
You Can just count the blocks
B: has 24 and D has 24 which both of them are between 30 and 20
Answer:
angle 2 = 37º
Step-by-step explanation:
When two lines intersect they make vertical angles, which are angles directly across from another. Vertical angles are always congruent.
Z=0 I think it’s the answer
Answer:
You aren't asked which variable to solve for.
If we're solving for x then
4x = 12y -8
x = 3y - (8/4)
If we're solving for y
-12y = -4x -6
12y = 4x +6
y = (x/3) + (1/2)
