Answer:
5p
Step-by-step explanation:
p+4p can be written as 1p+4p. And 1p+4p=5p because 1+4=5.
You would use the Pythagorean Theorem a²+b²=c² and re-arrange to get a²=c²-b² then you would put the numbers in and get a²=130²-50² so a²=14400 and if you square root that you get 120. So the height of the mast is 120 feet.
Not doubling any numbers there are 46
To find x we are gonna use the cosine formula.
Cos 0 = adj/hyp
0 represents theta
Cos 0 = adj/hyp
Cos 0 = 25/40
Convert 25/40 to decimal from
25/40 = 0.625
On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.
Cos-1 0 0.625
= 51.31 degrees
x is therefore 51.3 degrees to the nearest tenth
