Answer:
use the explicit rule
Step-by-step explanation:
3/4 divide by 5 is equal to 3/20
Answer:
It's angle ABE
Step-by-step explanation:
It's supplementary because the sum of the measurements of both angles EBC and ABE is 180°
Answer:
See below
Step-by-step explanation:
It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h
but you can use Heron's Formula
Area = sqrt( s (s-a)(s-b)(s-c) )
s = semi- perimeter = (3+6+7)/2 = 8
Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2
