Answer:
3/2 = 1/ 1/2
Step-by-step explanation:
1 1/5 divided by 4/5 is 1 1/2
Answer:
sin X = 12/13
cos X = 5/13
tan X = 12/5
Step-by-step explanation:
Recall the definitions as follows:
For a right triangle (i.e one angle is 90 deg) with one of the angles X
sin X = opposite side / hypotenuse
cos X = adjacent side / hypotenuse
tan X = opposite side / adjacent side
In our case for angle A, the following applies:
opposite = 36
adjacent = 15
hypotenuse = 39
hence
sin X = opposite side / hypotenuse = 36/39 = 12/13
cos X = adjacent side / hypotenuse = 15/39 = 5/13
tan X = opposite side / adjacent side = 36 /15 = 12/5

X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
r=8
Answer:
72 cm
Step-by-step explanation:
Find the radius using the given information
308=1/2(πr^2)
r^2=616/π
r=14
The perimeter is πr + 2r so plug in 14
π(14) + 2(14)
43.96+28=71.96
