[(14,7 + 5,9) x 5,8] / 2 = 59,74 cm^2
first is 86
we know because of the sum of the interior angles of a triangle being 180, and that 5 + 6 =180
The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
G(-1) = -1+3
= 2
F(2) = 5(2) - 10
= 0
Answer:
it would be 36
