2^3 is equivalent because if you count the number of twos there are in the parentheses its 3.
To find <ABC, the first thing you would need to do is to find angle DBA and the value of x
As <DBE is a right angle, <DBE is on the same straight line as well,meaning that it would be 90° , a right angle as well.
It also mean that the total sum of the angles unknown would be 90°
To find x,we need to set up an equation:
(2x+14)+ (x+7) = 90
3x+21 = 90
3x = 69
x = 23
Thus,<ABC would be
(23)+7
=30°
Hope it helps!
Answer: Ordinal
Step-by-step explanation:
We know that the ordinal scale is a level of measurement which is used when we are ordering attributes according to their ranks or preferences.
