How do I find the missing side length?

Answers

Answer 1

Answer: adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a

cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3

tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3

Answer:
a=4/3
b=2√3 /3

Answer 2

Answer: subtract the to sides

Adam runs 4 miles in 20 minutes. How many miles does he run in 1 hour?

Answers

Answer: Adam will run 12 miles in 1 hour.

Step-by-step explanation:

Ok, so we know 4 miles in 20 minutes, correct?

Multiply 20x2. You will get 40. Then, multiply 4x2. That is 8. So in 40 minutes he ran 8 miles. So if we multiply 20x3, we would get 60 minutes which is an hour. So we need to multiply 4 by 3–12.
