The figure of the triangle is missing, so i have attached it.
Answer:
BC = 5.4
Step-by-step explanation:
From the attached triangle image, we are given 2 angles, but we need to find the third angle before we can find BC.
We know that sun of angles in a triangle is 180°.
Thus;
∠A = 180 - (∠C + ∠B)
∠A = 180 - (24 + 130)
∠A = 26°
Now, from sine rule, we can find BC.
BC/sin A = AB/sin C
Thus;
BC = (AB sin A)/sin C
BC = (5 × sin 26)/sin 24
BC = 5.389
Approximating to the nearest tenth gives;
BC = 5.4
