Pls asap given: △abc, m∠b=120° ab=6, bc=10 find: area of △abc you!

Correct answer is : Area of triangle is

Solution:-

We can do it in 2 methods.

Method 1:-

Given that AB=6, BC=10 and m∠B = 120

Then area of triangle =

Let us assume AB is base and D is an altitude from C onto AB.

Then sin(60)=

          CD = BC sin(60)

Hence height = =

Hence area of ΔABC = sq.units

Method2:-

Area of triangle =

Here a= BC=10, c=AB=6.

Hence area of triangle = sq.units

i’m sorry but i don’t know sorry
