Write 2 Sine And 2 Cosine Equations For The Triangle ABC You Dont Need To Solve For X Amp Y class=

Sagot :

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

diagram (triangle)

Step 02:

trigonometry:

1. equations:

opposite = y

adjacent = x

hypotenuse = 7

angle = 24°

sin θ = opposite / hypotenuse

sin 24 = y / 7

cos θ = adjacent / hypotenuse

cos 24 = x / 7

2. equations:

opposite = x

adjacent = y

hypotenuse = 7

angle = 66°

sin θ = opposite / hypotenuse

sin 66 = x / 7

cos θ = adjacent / hypotenuse

cos 66 = y / 7

That is the full solution.
