Hypotenuse of 15 and opposite of 12For this triangle what is the cos
1 answer:
<h3>Given</h3>
right triangle with side "a" = 12 and hypotenuse "c" = 15
<h3>Find</h3>
cos(∠A)
<h3>Solution</h3>
The Pythagorean theorem tells you
... b = √(c² - a²) = √(225 - 144) = √81 = 9
The definition of the cosine tells you
... cos(A) = b/c = 9/15
... cos(A) = 3/5 . . . . . . reduce the fraction

24
Step-by-step explanation:
f(x)=5x^2-7x
substitute x to 3
f(3)=5(3)^2-7(3)
f(3)=5(9)-21
f(3)=45-21
f(3)=24
