Answer:
A. SinA=10/26 B. CosA=24/26 C. TanA=10/24 D. TanB=24/10
Explanation:
You really need to remember this formula for trig: Soh Cah Toa
S=Sin O=Opposite H=Hypotenuse
C=Cosine A=Adjacent H= Hypot.
T=Tangent O= Oppo. A=Adjac.
Now if we take Soh, what it basically means is that the sine is equal to the opposite over the hypotenuse, same thing for the others, cosine is equal to the adjacent over the hypotenuse and tangent is equal to the opposite over adjacent. When you have a letter such as A or B in front of sin cos or tan, it represents which angle on the triangle does this imply to, if that makes sense. For example, for sin A you use Soh to find the ratio, opposite = 10 and hypotenuse = 26, so 10/26. Same thing for Cos A, adjacent = 24 and hypotenuse = 26. You apply the same thing for tan, but something happened, there is a TAN B, so what that means is that you go to angle B, and you apply the toa formula, opposite= 24 and adjacent = 10 so 24/10. Hope this answers your question. MAKE SURE YOU REDUCE YOUR RATIOS. :)
