641 squf units

Answer 1

c) 61.8 square units

Explanation:

just took the test

Answer 2

`A=61.8\ units^2`

Explanation:

see the attached figure to better understand the problem

we know that

The area of triangle ABC applying the law of sines is equal to

`A=(1)/(2)(AC)(BC)sin(C)`

substitute the given values

`A=(1)/(2)(10)(13)sin(72^o)`

`A=61.8\ units^2`
