Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.
sin(I) = 
To solve, you can use your calculator and the inverse sine function (sin^-1).
I = sin^-1()
I = 61 degrees
Hope this helps!
It is already in simplest form
Answer:
mean = 52
Step-by-step explanation:
Just add all four together and divide by 4. That's the mean.
Sum (49 + 43 + 53 + 63) = 208
Mean = 208 /4 = 52
Answer:
B) h(x) = -1/4(x - 6)(x + 3)
Step-by-step explanation:
Zeros of a function:
Given a polynomial f(x), this polynomial has roots 
such that it can be written as: 
, in which a is the leading coefficient.
In this question:
Concave down, so 
, which excludes options c and d.
Roots at x = 6 and x = -3. So
So option B.
