That is hard i wish you luce
Answer:
1. 7 sqrt(2)
2. (30 sqrt(7))/7
Step-by-step explanation:
Simplify the following:
sqrt(50) + sqrt(8)
sqrt(50) = sqrt(2×5^2) = 5 sqrt(2):
5 sqrt(2) + sqrt(8)
sqrt(8) = sqrt(2^3) = 2 sqrt(2):
5 sqrt(2) + 2 sqrt(2)
5 sqrt(2) + 2 sqrt(2) = 7 sqrt(2):
Answer: 7 sqrt(2)
_____________________________________________
Simplify the following:
30/sqrt(7)
Rationalize the denominator. 30/sqrt(7) = 30/sqrt(7)×(sqrt(7))/(sqrt(7)) = (30 sqrt(7))/7:
Answer: (30 sqrt(7))/7
Answer:
B.
Step-by-step explanation:
Vertical angles are an opposite pair of angles created by two intersecting lines. Angles 2 and 5 are a pair of angles, on opposite sides, created by the two intersecting lines w and v. Therefor, angles 2 and 5 are equivalent. B is the answer.
