Remember "SOH CAH TOA"
Sine = (Opposite/Hypotenuse)
Cosine = (Adjacent/Hypotenuse)
Tangent = (Opposite/Adjacent)
In this case, we will be using cosine, and our equation will be
So firstly, cross-multiply.
Next, divide both sides by cos(28), and your answer will be
Answer:
a.)12.5
Step-by-step explanation:
You have a triangle with a 90º angle, you can apply the laws of the triangles on the triangle, and the chosen would be cosine.
Cosine=
Cosine 28º=
x=
x= =12.45
x=12.5
