Question

Find the values of the sine, cosine, and tangent for angle A

Answer 1

sin = p/h.

cos=b/h

tan =p/b

pythagoras

h^2=p^2+b^2

here

h=5

p= 3

b=4

Answer 2

sin(A)=3/5

cos(A)=4/5

tan(A)=3/4

Explanation:

length of the other side is 5 using pythagorean theorem

sin= opposite/hypotenuse

cos= adjacent/hypotenuse

tan= opposite/adjacent

opposite angle A- 3

adjacent angle A- 4

hypotenuse- 5
