Answer:
D
Step-by-step explanation:
If it is a right triangle, by pythagorous theorem, 39^2 = 36^2 + 15^2
or, 36^2 + 15^2 - 39^2 = 0
Answer:
If its radius is 9 cm, it’s circumference would be two times radius times pi equal to 18 pi. Also its area is pi R squared which is equal to 81 pi. Circumference = 18 pi Area = 81 pi Area is 4.5 times greater than the circumference. The answer is C.
Answer:
A = 77.32
Step-by-step explanation:
Since this is a right triangle we can use trigonometric functions
sin = opposite side/ hypotenuse
sin A = 80/82
sin A =40/41
Take the inverse sin of each side
sin^-1 (sin A ) =sin ^-1 (40/41)
A =77.31961651
Rounding to the nearest hundredth
A = 77.32
