Answer:
sin X = 12/13
cos X = 5/13
tan X = 12/5
Step-by-step explanation:
Recall the definitions as follows:
For a right triangle (i.e one angle is 90 deg) with one of the angles X
sin X = opposite side / hypotenuse
cos X = adjacent side / hypotenuse
tan X = opposite side / adjacent side
In our case for angle A, the following applies:
opposite = 36
adjacent = 15
hypotenuse = 39
hence
sin X = opposite side / hypotenuse = 36/39 = 12/13
cos X = adjacent side / hypotenuse = 15/39 = 5/13
tan X = opposite side / adjacent side = 36 /15 = 12/5
Hey there! Welcome to Brainly.
Let's solve using order of operations (PEMDAS), which is Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
First, we solve the parentheses.
9+6÷6
Now we take care of the division.
9+1
We add.
10
Therefore, your answer is 10
I hope this helps!

Answer:
-1.75.
Step-by-step explanation:
The z-score = (n - m) / d where n is the value (13) m = mean and d = standard deviation.
= (13 - 20) / 4
= -1.75 (answer)
