Question

I need help on 9, 10, 11, and 12, on attached document, thanks

Answer 1

well. on first one, the triangle must add to 180...

Answer 2

On 9, it has to be 54.5. Because that is the only thing that will let three angles add up to 180.

Answer 3

if it is isosceles, two of the angles have the same measure.....

Answer 4

c'mon basic... you can answer it ALL

Answer 5

BTW - you should be typing out the questions separately into different posts.

Answer 6
