Answer: The correct option is C
Step-by-step explanation:
Looking at the right angle triangle ABC, three sides are known and the angles are unknown. To find sin A, we will take A to be our reference angle, we will have the following
Hypotenuse = AB = 26
Opposite side = BC = 24
Adjacent side = AC = 10
Applying trigonometric ratio
SinA = opposite/hypotenuse
SineA = 24/26
To find cos A, A remains our reference angle, we will have the following
Hypotenuse = AB = 26
Opposite side = BC = 24
Adjacent side = AC = 10
Applying trigonometric ratio
CosA = adjacent/hypotenuse
CosA = 10/26
The correct option is C
