The area of a rectangle, which I'm assuming it is, is A= lw. Where "l" is length and "w" is width.
The answer should be D). A) has no solutions and B) and C) have 2 solutions.
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:
Step-by-step explanation:
By definition, the sum of the interior angles of a triangle is 180 degrees.
You can observe that the given triangle has an angle that measures 90 degrees and it also has two equal sides.This means that the other two angles are equal.
Knowing this, you can conclude that the triangle is an Isosceles Right Triangle and the other angles measure 45 degrees each.
Therefore, now you know that:
Solving for "x", you get that its value is:
And for the other angle:
Solving for "y", you get that its value is the following:
Well, this is a broad question but I would say pie. Pie is used very early on in secondary school and therefore a lot of people already know about it and how to use it. But for example if your a banker E would be more important as banks use e to calculate interest.
Hope this helps, have a great day.
