Question

How do you find the area of `triangle ABC` given a=326, c=157, `mangleB=72`?

Answer 1

`24338.5`

Explanation:

Area of a triangle - "side angle side" (SAS) method :

Area `=1/2*a*b*sinC`
where `a,b` are the two known sides and `C` is the included angle.

Given `a=326, c=157 and angleB=72`,
`=>` Area `= 1/2*a*c*sinB`
`=>` Area`=1/2*326*157*sin72=24,338.5` `unit^2`
