Answer:
A: adjacent angles: The angle ∠CFD & ∠DFE are directly next to each other, making them <em>adjacent angles</em>.
B: Complementary angles: Note that m∠BFC measures at 90°. m∠BFE is a straight line, with 180°. This means that ∠BFE - ∠BFC = ∠DFE.
180 - 90 = 90 ∴ m∠DFE = 90°

Answer: x=11
Step-by-step explanation:
The lines are parallel, which you can tell by the two arrows. 4x-8 is a corresponding angle to 3x+3, meaning they are congruent.
4x-8 = 3x+3
x=11
Answer:
P(green or purple) = 0.576
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
32 + 47 + 21 + 25 = 125 blocks.
Of those, 47 + 25 = 72 are green of purple
P(green or purple) = 72/125 = 0.576
First divide both sides by 5. Then you get the answer. -0 or 0 I'm not sure tho
