Question

Give the area of this triangle where C=118deg, b=130km, a=75km?

Answer 1

joeschmo has the correct formula but the wrong answer.

"The area of a triangle is half the product of two sides times the sine of the included angle. "

A = (1/2)(a)(b)(sin C)

A = (1/2)(75 km)(130 km)(.981952169)

A = 4787 sq. km.

Answer 2

Well, I used an equation that I didn't know existed until now, but it gives the Area of a triangle as equal to 1/2absinC

so, from there i just plugged everything in and i got 4304 km^2

Hope that helps!

(ps, this is so not geography haha)
