Does anyone know this answer??

Obtuse

Step-by-step explanation:

One of the angles is above 90 degrees

Its not acute or right.

It’s the size of obtuse

No idea what equilateral

For this question first you should find the area of the triangle so you should say:
3*6/2 = 18/2 = 9 ft
now you should find the area of the rectangular so you should say:
16*8 = 128 ft 
now you should add them together so you will have:
128 + 9 = 137 square foot :)))
i hope this is helpful
