Sin=opposite÷hypotenuse

cos=adjacent÷hypotenuse

tan=opposite÷adjacent

hypotenuse is the longest side, the opposite is the side that is opposite of the angle you're trying to find, and the adjacent side is the side that is not the hypotenuse or opposite.

plug it into your calculator. it is very simple :))

for future reference if you attach a photo it will be easier for people to help you.

Rectangule and semicircle

Area of rectangle :

Length * width

Length = 8m ; width = 3m

Area = 8 * 3 = 24m²

Area of semicircle = 1/2 πr²

Radius, r = 3m

A = 1/2 * 3.14 * 3²

A = 1/2 * 3.14 * 9

A = 14.13 m²

Area of patio :

(24 + 14.13)m²
