A side of the triangle below has been extended to form an exterior angle of 156°. Find the value of x.

24°

Step-by-step explanation:

156° and x° form a straight line, and angles that form a straight line sum to 180°

Thus, 156° + x° = 180°

=> x° = 180° - 156° = 24°

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5 1/10

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
