2. We want to find the hypotenuse.
We know an angle to be 23 degrees.
We were also given the side opposite to this angle to be 1200km.
Therefore we use the sine ratio.
Answer:
G. 12
Step-by-step explanation:
Rachel = x
Trina = y
x = 2y - 6
x = (2x9) - 6
x = 18 - 6
x = 12
Answer:

Step-by-step explanation:
Given
See attachment for illustration
Required
Find x
To do this, we apply Pythagoras theorem.
From the attachment, the length of the hypotenuse is 16.7ft
While the length of the opposite/adjacent is 8.9ft
Length x is calculated using:



Take square roots


43/12 can be
3 7/12
