Question

The area of triangle abc = 64cmsq given ab= 11cm bc=15cm find abc

Answer 1

Answer:

To determine the measure of the angle B, we'll have to use

the following formula that gives the area of triangle:

A =

leg1*leg2*sine of the angle included/2

Since the lengths of

AB and BC and the value of the area of triangle are known, we'll replace them within the

formula above:

64 = 11*15*sin

B/2

We'll multiply both sides by

2:

128 = 165*sin B

sin B =

128/165

sin B = 0.775

B =

50.80 degrees

The included angle ABC measures

50.80 degrees.
