Answer:
62.79cm
Step-by-step explanation:
<u>We are using TRIGONOMETRY</u>. To find the area of a triangle with 2 lengths and a non-right angle, we will use the sine rule.
Area of Triangle = 1/2 * a * b * sin(c)
(Where a & b represent our lengths, and sin(c) represents our angle.)
Area of Triangle = 1/2 * 10 * 13 * sin(105)
Area of the Triangle = 62.79cm
