Question

2) Solve each problem with right angle at C:.

a) Find all sides and angles when B = 67º and c=16.
b) Find all sides and angles when b= 2 and c=6

Answer 1

Explanation:

a.)

<A = 90 - 67 = 23* A = (a^2 + 14.72^2 = 16^2) = a = 6.25

<B = 67* B = (sin67 = b/16) = sin67*16 = 14.73

<C = 90* C = 16

b.)

a = (a^2 + 2^2 = 6^2) = a = 5. 66 <A = (cosA = 2/6) = 70.53*

b = 2 <B = 90-70.53 = 19.47*

c = 6 <C = 90*
