#8= b

#9= b

#10= a

Step-by-step explanation:

the first question asked if the triangles sides match up to 240, the answer would be no, since the  interior angles have to equal 180 and the outsides equal to another 180 making the entire thing 360( which is not near 240).

the second question is true because obtuse angles will be unequal always.

the third question asked if the sum of the angle equal to 90degrees in a right triangle. this is not true since the angles all must equal to 180. only the right part of a right triangle can have the 90 degree angle.

any part of this could be wrong but hope this helps!

okay so 15.15 *()5: +5/6
