Your answer is x = 2.92 = 3.
To answer this question you need to use trigonometry, so the first step is to identify the hypotenuse, opposite, and adjacent.
Because the angle 73 is in the bottom corner next to the length x, we know that the length x is the adjacent. The length 10 is opposite the right angle so this must be the hypotenuse.
We know that cos(θ) = adjacent/hypotenuse, so we can substitute in what we know:
cos(θ) = adjacent/hypotenuse
cos(73) = x/10
Now we can rearrange for x:
cos(73) = x/10
× 10
cos(73) × 10 = x
Finally we just type this into the calculator and get the answer as 2.92 or 3.
I hope this helps!
Answer:
D. (4,3)
Step-by-step explanation:
I calculated it logically
(5 x 6) + 7 = 37
(5 + 7) x 6 = 72
(6 - 7) / 5 = -1/5
Remember
so let's rewrite them
25=5^2
so
yep, that's definitely true
