4, 8, 10, 7, 3, 4... Those r in order from top to bottom! it's all about the simplification!
Answer: 10
Step-by-step explanation:
a 30° - 60° - 90° triangle has a side ratio of 1:√3: 2, meaning the side length across from the 30° is 1, the side length across from 60° is √3, and the side length across from 90° is 2
if you multiple the 1 * 5 = 5 (the 5 side length in the diagram), then also multiple (5 * √3 = 5√3) and (2 * 5 = 10)
since you're looking for the hypotenuse (the length across the 90°), the answer would be 10 (2 * 5 = 10)
*this method can work for any 30° - 60° - 90° triangle
you can also use trig:
sin (30°) =
(now just solve for x)
x * sin (30°) = 5
x = 
x =
( because sin (30°) = 1/2 )
x = 5 *
= 10
*either method works!
Answer:
It would be 2.17391304348 but you can round it to the nearest tenths or hundreths, whatever you choose
Step-by-step explanation:
If you want to round it to the nearest tenths, then it would be 2.2
If you want to round it to the nearest hundreths, it would be 2.17
