Answer:
b: 4
Step-by-step explanation:
i took the test on edge 2020
A triangle can only equal 180 so you take 180-50 and get 130 then you divide 130 by 2 your answer is 65 X =65
The answer is d, when you divide 45 by 54 you get 0.833333333333.... the line above the 3 means that there is infinite number of threes
Answer:8
Step-by-step explanation: it cannot be 2, 6, or 5 because they are all less than 7.
Well, sine is

,
but from the angle C, the opposite side, the one facing it off, is the side
AB, and we dunno what the side AB is
however, we know the hypotenuse is 8, and the adjacent side is 7,
and is right-triangle, thus, let us use the pythagorean theorem,

now, that we know what the opposite side is, that is AB, then
we can find the sine of angle C
