Answer:
Part 1) Sin ϴ = 5/13, Cos ϴ = 12/13, Tan ϴ = 5/12
Part 2) Sin A = 4/5, Cos A = 3/5,Tan A = 4/3
Explanation:
we know that
In a right triangle
The function sine of an angle is equal to divide the opposite side to the angle by the hypotenuse
The function cosine of an angle is equal to divide the adjacent side to the angle by the hypotenuse
The function tangent of an angle is equal to divide the opposite side to the angle by the adjacent side to the angle
Part 1)
Find the Sin ϴ
Sin ϴ=5/13
Find the Cos ϴ
Cos ϴ=12/13
Find the Tan ϴ
Tan ϴ=5/12
Part 2) we know that
In the right triangle ABC
Applying the Pythagoras Theorem
Find the hypotenuse AB
Find the Sin A
Sin A=8/10=4/5
Find the Cos A
Cos A=6/10=3/5
Find the Tan A
Tan A=8/6=4/3
