X= -2.8596 or rounded up -2.86 is the correct answer.
Answer:
25/64
Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
Answer:
4/5.
Step-by-step explanation:
The right triangle with this angle in it has sides 3, 4 and 5. ( 5^2 = 3^2 + 4^2).
So as sin∅ = 3/5, the opposite side to angle ∅ is 3 , the hypotenuse is 5 and the adjacent side must be 4 units long.
So cos∅ = adjacent side/hypotenuse = 4/5.
