Triangle BCD is Isosceles triangle.
Angles C and B are the same and equal 36 degrees. Angle D= 180-(36•2)=180-72=108
Good luck.
Rounding to the nearest million is just looking at the 100,000's place, and seeing if it's bigger than 5 or not. if it is you round to the number up to the next million and if it's not you round the number down to to the same million. In your case it rounds up to 2,000,000 because of the the 100,000's place is a 5 so you round up
6x-24=48
+24 +24
6x=72
72/6
X=12
If you would like to know what number is 10 less than 67, you can calculate this using the following step:
