Answer:
AB equals 25
Step-by-step explanation:
1( you take ED and the 5 and say of 5.
2( then you count all the letters that stand for numbers and count them.
3) after you count them how many ever there are then you take that number which was 5 too.
4(after you find that number which is number 5 you multipliy 5 and 5.
5(after you multipliy then you should get 25 because 5x5 is 25.
And there you go thats the answer step by step.
In order to find the length of ?? (let's call this distance x), let's first find the value of Angle A.
The cosin of Angle A is Adjacent / Hypotenuse, or 40 / 50. Using this Info:
cos (A) = 40/50
cos (A) = .8
With this crucial piece of info, we can find the Total length of A-D (Point D being the point above C), by finding its relation to side AC (length of 50 + 70 =120 ft)
Cos (A) = adjacent / hypotenuse
Cos (A) = AD / (120) We know that cos (A) = .8
.8 = AD / (120) Multiply both sides by 120
96 = AD
We're almost there! Remember that we're trying the find x (?? in the diagram).
x + 40 = 96
x = 56 ft
