well first off do you understand what it means when it says the "square root of x"?
Answer:

Step-by-step explanation:
Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.
Apply the trigonometric ratio formula to find m < C.
Adjacent side = 7
Hypotenuse = 8
Trigonometric ratio formula to apply would be:




(To nearest tenth)
Step-by-step explanation:
it has been awhile since ive done this.
so a line =180
so to find the other angle you simply subtract 120 from 180.
Mm im not 100% sure but im pretty sure if you take 10 + 28 and get 38 and then 760 - 38 should be the answer
Soo i think the answer should be 722 meters or whatever
all of them???
