Answer: 1
Step-by-step explanation:
Answer:
b = 7√3
Step-by-step explanation:
This 30°- 60°- 90° triangle has the proportions:
side opposite of the 30° angle = x
side opposite of the 60° angle = x√3
side opposite of the 90° angle = 2x
____________________________
Given the side opposite of the 30° angle which is 7 units long, this can be thought of as x. Knowing the proportions of the other sides, we can find b knowing that this is the side opposite of the 60° angle which is x√3.
Since x = 7, x√3 = 7√3, and therefore
b = 7√3.
31 = -4v - 5
31 (+5) = -4v -5 (+5)
36 = -4v
36/(-4) = -4v/(-4)
36/ -4 = v
v = -9 is your answer
hope this helps
