Answer:
D.) 12/5
Step-by-step explanation:
tangent is opposite over the adjacent side so the opposite of x is 24 and the adjacent is 10 so 24/10 divided by 2 gets you 12/5
f(x) = -x + 2
f(-1) This means that they want you to find the value of f(x) or y when x = -1.
f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1
f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)
f(-1) = 1 + 2
f(-1) = 3
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.
So then you put 3 out the parentheses. 3(----).
Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.
So then this is what you get, 3(27m-16mn)
Hope it helps you!!!
So since angle A is 120, so angles B+C=60 because there are 180 degrees in a triangle. So B:C is 2:1. So angle B is 40 and angle C is 20.
