Answer:
Step-by-step explanation:
Equation:
Jalil says it is not possible to isolate x because x has a different unknown coefficient.
Victoria t. Victoria believes there is a solution
Solving the equation:
So, this shows x can be isolated .
Victoria was right .
It was not possible to isolate x if the coefficients of x would be same .
But in the given equation the coefficients of x are not same .
So, Victoria is right.
Answer:
40 feet
Step-by-step explanation:
Given : The deck is at a height of 520 ft. She sees her friend on the ground below at an angle of depression of 85.6 degrees.
To Find : What is the distance between the two? Round your answer to the nearest tenth of a foot.
Solution :
Refer the attached figure
Height of deck =AB =520 ft.
Angle of depression ∠C = 85.6°
We are supposed to find length of BC i.e. distance between two.
We will use trigonometric ratios :
Thus the distance between two is 40 feet
