Answer:
The measure of the longer base is:
9 centimeters
Step-by-step explanation:
We know that the area of a trapezoid with height h and two parallel bases b and b' is given by the formula:
Here we have:
The area of a trapezoid is 30 square centimeters. The height is 4 centimeters. The shorter base measures 6 centimeters.
i.e.
Step-by-step explanation:
5.7 of anything minus 3.9 of the same thing leaves 1.8 of them.
It is a percentage because it can be written as a fraction
The statement that <A > <C and <B > <D has been proved
<h3>How to prove that <A > <C and <B > <D?</h3>
In geometry, the side length opposite the largest angle is the longest side.
Similarly, the side length opposite the smallest angle is the shortest side.
From the given figure of quadrilateral, we have the following sides in increasing order:
- Side length AB
- Side length BC
- Side length AD
- Side length CD
The angles opposite the side lengths are:
- Angle D
- Angle B
- Angle C
- Angle A
This means that:
<A > <C and <B > <D
Hence, the statement that <A > <C and <B > <D has been proved
