The cosecant(reciprocal of Sine)- opposite / hypotenuse→ hypotenuse / opposite The secant(reciprocal of Cosine)- adjacent / hypotenuse→ hypotenuse / adjacent The cotangent(reciprocal of Tangent)- opposite / adjacent→ adjacent / opposite
Lastly, the reciprocal of trig ratios.
We just need to switch the regular trig ratios.

What is the sine of <P ?
Thanks for watching hope you learning things
Find the side AB _______
Round to the nearest hundredth
Cos(45) = AB / 13 Cos(45) ・ 13 / 1 = AB / 13・13 / 1 Cos(45) ・13 = AB 9.19 = AB
Side AB = 9.19
Find the angle of Z ______
tan-1 (4 / 9)
First, we should determine what trigonometric ratio could be used from the given. In this case, we could use the cosine from angle A.
Let's solve for a side in the right triangle using the trigonometric ratios.
