we are given
△ABC
we can use area of triangle formula
we have
AB=6
BC=10
m∠B=120°
so, we can plug it
..............Answer
In this right triangle<span>, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest </span>side<span> of the </span>triangle<span>. </span>To find<span> the </span>length<span> of leg a, substitute the known values into the Pythagorean Theorem.
