Question

Given that

a
= 6 cm and
b
= 11 cm, work out
θ
rounded to 1 DP.

Answer 1

56.9°

Explanation:

Assuming you mean a and b as the legs of a right triangle and θ as the bigger angle in a right triangle, we can work out easily that

cos θ = 6/11

so θ ≈ 56.9°(to 1 d.p.)

Answer 2

Not enough information in order to solve. Need to know where a and b are
