B, there's only two kinds of acute triangles ands that's a 45,45,90 and a 30,60,90.
The answer is 3 because x is -7. I hope this helps!
For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.
Answer:
2 sqrt(13)
Step-by-step explanation:
We can find the hypotenuse using the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
4^2 + 6^2 = c^2
16+36 = c^2
52 = c^2
Taking the square root of each side
sqrt (52) = c
sqrt(4*13) = c
2 sqrt(13) = c
