I think it’s B (0, 0) (5, -3), (4, 1).
Perimeter of base x height. So, (3+4+5)x6. 12x6=72. 72 is the surface area.
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
---> by addition angle postulate
substitute the given values

solve for x

<em>Find the measure of angle MON </em>
substitute the value of x
So you know that the area is (b*h)/2
A = (6,6*4,9)/2 = 32,34/2 = 16,17 cm^2
