Answer:
cos(θ) = (5√74)/74
Step-by-step explanation:
The length of the hypotenuse is given by the Pythagorean theorem:
h = √(5² +7²) = √74
The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:
cos(θ) = 5/√74 = (5√74)/74
Answer:
I just need points I don't know your answer
Step-by-step explanation:
To reduce a number by 12% we can simply multiply it by 0.88. If we repeat this 5 times we get 8, 7.04, 6.1952, 5.451776, 4.79756288, 4.2218553344.
We end up with 4.2218553344.
I think this is right.
