Angle D and angle G are the base angles, which means they are equal. If D = 18, then G = 18. Since the sum of the angles of a triangle equals 180 degrees, subtract 18 + 18 from 180 to get angle O.
180 - 36 = 144
Angle O = 144
Hope this helps =)
I'm pretty sure that your answer is the Distributive Property, if I were you, I'd check your notes if you have notes or anything, and THEN, search it up. Just to make sure. I'm not always a hundred percent sure of my answer, but, I *THINK* it's the distributive property.
-3(x+4)+6
-3x-12+6
-3x-6 <= that’s the answer but just in case you want to find what “x” is:
-3x-6=0
add 6 to both sides
-3x=6
divide -3 to both sides
x=-2
