Problem solving in trig, help?

Answer 1

Answer:

13170 to the nearest whole number.

Step-by-step explanation:

We can use Heron's formula to do this:

Area =  √[s(s-a)(s-b)(s-c)]    where s = the semi-perimeter.

s =  (155+175+260)/ 2

= 295

Therefore the Area = √ 295(295-155)(295-175)(295-260)

= √173460000

=  13170.42.
