Question

In a triangle ABC angle b=90°. If AB=14 cm and AC=50cm then tan A equals

Answer 1

Answer:

In triangle ABC, AB = c = 3, AC = b = 4 and <BAC = 60 deg. What is BC = a?

We can apply the cosine formula

a^2 = b^2 + c^2 - 2bc cos C

= 4^2+3^2–2*4*3*cos 60

= 4^2+3^2–2*4*3*0.5

= 16+9–12

= 13

BC = a = 13^0.5 = 3.605551275 cm
