If triangle ABC is equilateral,solve for X56x-308
Answer: m∠D = 65°
Step-by-step explanation:
The best solve method for problems like this is say the sum of the angle values equals 360.
2x-15+2x-15+x+x = 360
Then from here you just simplify.
4x+2x-30 = 360
6x = 390
x = 65
So the measure of Angle D equals 65 degrees.

I did 3.6^2 and then multiplied it by 6
Hope this helps :)
I'm gonna say 400 because
2,316/6=386 which is closest to 400
