Equal lines

Step-by-step explanation:

Can you help me with this question in geometry?

Svetllana [295]

I believe this just uses the Pythagorean Theorem. A^2+B^2=C^2. So:
15^2+B^2=25^2. Simplified this is,
225+B^2=625
625-225=400
B^2=400
√ B=<span>√ 400
</span>B=20

Suppose you spin the spinner and toss a coin. What is the probability of NOT heads and NOT 4? A) 1/8 B) 3/8 C) 5/8 D) 7/8

7nadin3 [17]

I think the answer is B) $\frac{3}{8}$ . You can figure this out by multiplying the possible outcomes of the coin by the spinner (4*2) and find the amount of outcomes that are not what you are looking for (3) and put that over the product. (3/8)

Hope this helps
