Write the expression as a constant , a single trigonometric function, or a power of a trigonometric function. sin x cos x/ tan x

cos²x

Step-by-step explanation:

Using the trigonometric identity

• tanx = , then

=

= sinxcosx ×

cancel the sinx in the multiplier with the sin x on the denominator

= cos²x

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
