I hope this helps you
let's find AB
AB=square root of 2^2+3^2
AB=square root of 13
cosO=2/sqrt13
sinO=3/sqrt13
tgO=3/2
ctgO=2/3
When simplified, the answer is 1
I have done this question yesterday it is 1 and 3
Solving equations is a basic skill that you must master to deal with a
lot of problems in mathematics, physics, chemistry, administration,
economy, and almost every activity where you need to use a formula or a
model. to solve for h, you follow these steps: 1) multiply both sides by
2 => 2A = (a+b)h; 2) divide both sides by (b+a) => 2A/ (a+b) = h.
So the answer is: h = 2A / (a+b).

L = 5W - 10
5W = L + 10
W = 1/5(L + 10)
Area = L x W
240 = L(1/5(L + 10)
L^2 + 10L = 240(5) = 1200
L^2 + 10L - 1,200 = 0
