Answer:
It should be 9+h+2
Step-by-step explanation:
P=44+66+88/2=198/2=99
With Heron formula:
S=root 99*(99-44)(99-66)(99-88)=root 99*55*33*11=root 1976535= 1405.8929.....=1405.9
Answer:
Step-by-step explanation:
because <u>c</u> is shorter than<u> a</u> we know C is a smaller angle than A
so the first choice is out.
use the law of cosines to find b
= 
=1681+400-1326.787871
= 754.21219
b= 
b= 27.46292
so the last choice looks good
$60
400 ÷ 7 = 57. 1428571429
Since that's not an option we estimate it. The closest number is $60 so, there's your answer!
I hope this helps! sorry if it's wrong :(
