Answer 12

Thanks

Answer 13

What about the second question?

Answer 14

Sum of 3x-5 and x + 7 should equal the full angle which in this case is a right angle = 90 degrees.
So just need to solve that equation for x. Makes sense?

Answer 15

Answer 19

3x - 5 + x + 7 = 90
4x + 2 = 90
....can you solve from here?

Answer 20

Yes

Answer 21

How about the second one?

Answer 22

Sum of all angles in a triangle equals to .... ?

Answer 23
