Answer:
The largest angle needed is .
Step-by-step explanation:
To determine the larges angle as required, let us apply the cosine rule.
=
+
- 2ab Cos C
Since in triangles, the longest side is opposite to the largest angle, then;
=
+
- 2(8 x 12) Cos θ
225 = 64 + 144 - 192 Cos θ
225 = 208 - 192 Cos θ
192 Cos θ = 208 -225
192 Cos θ = -17
Cos θ =
Cos θ = -0.08854
θ = -0.08854
= 95.07962
θ =
The largest angle needed is .
