Question

Please help I’m so confused and my parents are gonna kill me if I don’t get my homework done...

Answer 1

Ok I'll save ur life, thank me later-

52 + 56+x + 78 = 180(Since all angles in a triangle sum upto 180°)

=130 + 56+x =180

=186+x=180

=x=180-186

x=-6

56 + (-6)

=50

Hope it helps

Answer 2

X=-6

Explanation:

the sum of interior angels in a triangle is 180.

52+78=130

180-130=50

to get 56 to 50 x has to be negative

hope this helps :)
