Answer:
Step-by-step explanation:
sin x = opposite / hypotenuse
sin x = b / c
cos x = adjacent / hypotenuse
cos x = a / c
tan x = opposite / adjacent
tan x = b / a
A square root is equivalent to any number to the 1/2 exponent so you can simplify this to x^13/2
Like this you can make 13/2 A whole number fraction which is x^6 1/2
This is the same as x^6 × x^1/2 which can simplify to x^6 (square root of x) answer is D

Answer:
5x-10
Step-by-step explanation:
8x-3x-10
first you subtract 3from 8 and get 5 just add the x so your left with 10
ANSWER - 60%
WORKING OUT
3/5 is equal to 6/10 (doubled)
Which is also equal to 60%
(Each tenth is 10%)
