You remember from SOH CAH TOA that
.. Cos = Adjacent/Hypotenuse
.. cos(C) = 80/82 = 40/41 . . . . . . . . . . . seems to match the last selection
8(x + 5) = 56
first step id to distribute the 8 through the parenthesis
8x + 40 = 56
Answer:
12
Step-by-step explanation:
you subtract the ordered pairs on the sides. then the ones on the top and bottom. then you add all of the sides
Answer:
4
Step-by-step explanation:
If you mean root of x, 24-8=16
square root of 16=4
Answer:
16 cm
Step-by-step explanation:
A right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, use the pythagorean theorem to find the value for x.
let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The pythagorean theorem is: c^2 = a^2 + b^2.
18^2 = 7^2 + x^2324 = 49 +x^2
x^2 = 324 - 49 = 275So, x = sqrt(275) = 16.5 cm
