Question

Solve the following problem:

Given: ΔABC, m∠B = 120°
AB = 6, BC = 10
Find: Area of ΔABC

Answer 1

Answer:
`15√(3)`

Explanation:

One formula for the area of a triangle is a*b*sin(c)/2. This means that you multiply 2 sides of the triangle and the sine of the included angle (the angle formed by the conjunction of the two segments.) So we have
`6*10*sin(120)/2\\60/2*(√(3)/2) \\15√(3)`
