Answer:
B
Step-by-step explanation:
let base be b then height h = 2b + 4
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the height ) , then
A = b(2b + 4) ← distribute parenthesis
A = b² + 2b
When b = 16 , then
A = 16² + 2(16) = 256 + 32 = 288 in²
answer:
40°
explanation:
100 + 40 + 40 = 180 (sum of all the interior angles of a triangle)
45/2 can't be simplified.
Since there are 5 possible outcomes and 3 is only one of the outcomes, the probability would be 1/5 or 20%
