Answer:

cot(θ) = 24/7

Step-by-step explanation:

A suitable calculator can answer this nicely.

Perhaps you're expected to remember relevant trig identities.

tan(θ)^2 = sec(θ)^2 -1

cot(θ) = 1/tan(θ)

cot(θ) = 1/√(sec(θ)^2 -1)

cot(θ) = 1/√((25/24)^2 -1) = 24/√(25^2 -24^2) = 24/√49

cot(θ) = 24/7

Fd - m = 8<br> Solve for d<br> Please help!

Fudgin [204]

Answer:

$d=\frac{8+m}{f}$

Step-by-step explanation:

$fd-m=8$

Add m to both sides:

$fd-m+m=8+m$

$fd=8+m$

Divide both sides by f:

$\frac{fd}{f}=\frac{8+m}{f}$

$d=\frac{8+m}{f}$
