Answer:
addition property of equality
Step-by-step explanation:
59 = x-26
We add 26 to both sides using the addition property of equality

and so on, and then, you graph those x,y coordinates
If the problem was written x + 4x. We would know to add like the coefficients together and get 5x same thing with the radicals.
Answer: 138
Step-by-step explanation:

Answer:
The length of shadow is 69 foot.
Step-by-step explanation:
We are given a shadow of lighthouse.
Length of top of lighthouse to end of shadow is 90 ft.
Angle make at top of lighthouse is 50°
Distance from foot of lighthouse to end of shadow is x ft.
we need to find the length of shadow i,e x ft
Using trigonometry ration:




Hence, The length of shadow is 69 foot.
