Which of the following triangles are impossible to draw? Choose all that apply.
ioda
I would say a triangle with two right angles because a triangle's angles add to 180 degrees. If a triangle has two right angles, it means that two angles will be 90 degrees, which add to 180 degrees. A triangle must have three angles and sides, and it is not possible for the last angle to be 0 degrees.

Hope this helps

18 divide by 2 * 3/5-2 simplify show all work
liraira [26]

Answer:

9

Step-by-step explanation:

I would guess it looks like this - if not then tell me

\frac{18}{ \frac{2 \times 3}{5 - 2} }

2×3=6

5-2=3

Then there's only

\frac{18}{ \frac{6}{3} }

Which is equal to

\frac{18}{1}  \times  \frac{3}{6}  =  \frac{54}{6}  =  \frac{9}{1}  = 9
