Answer:

AD=BE

Step-by-step explanation:

Because AB and BC are equal, their lengths are also equal and also it is an Isosceles triangle. Therefore the midpoint of AB or the half of AB which is either AD or DE are equal. Vice versa for BC. So AD=BE

Answer:

Using mid point theorem, A line segment joining the mid points of the two sides of the triangle, is equal to half the length of the third side.

D and E are the mid points. Hence,

DE=

(6.4)

DE=3.2cm

△BCD is a right triangle. The length of the hypotenuse is 18 centimeters. The length of one of the legs is 14 centimeters. Wh

In a right triangle, this formula can be used:

a^2 + b^2 = c^2

when a and b are the legs and c is the hypotenuse.

Substitute the numbers from the problem into the formula.

14^2 + b^2 = 18^2

Simplify.

196 + b^2 = 324

b^2 = 128

b = square root of 128 = 11.3137...

When 11.313 is rounded to the nearest tenth, it is 11.3

The length of the other leg is 11.3 centimeters.

Hope this helps!

Let's start by breaking down the problem.

This is how it should look. ↓

$60$ ÷ $20$ ⇒ $+ 3$ ⇒ $x * 5^2$

What does that <em>x</em> mean? <em>x</em> is just a substituted value for the first 2 equations.

Now, we can solve.

$60$ ÷ $20$ $= 3$

Add 3

$3 + 3 = 6$

Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.

$5^2~or~5 * 5 = 25$
