One leg of a 45 - 45 - 90 triangle measures 10 inches. What is the length of the hypotenuse
djyliett [7]

Answer:

Therefore the length of the hypotenuse is 14.14 inches.

Step-by-step explanation:

Given:

The Triangle is of 45 -45 - 90

Length of one leg = 10 inches

To Find:

Length of the hypotenuse = ?

Solution:

The Triangle is of 45 -45 - 90 ..................Given

So For 45 - 45 - 90 Both the Legs of Triangle is SAME

i.e Longer leg = Shorter leg = 10 inches

Now in Right angle Triangle By Pythagoras Theorem we have

(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}

On substituting the values we get

Hypotenuse^{2}= 10^{2}+ 10^{2} \\\\Hypotenuse^{2}=200\\Square\ Rooting\ we\ get\\Hypotenuse=\sqrt{200}=10\sqrt{2}=10\times 1.414=14.14\ inches

Therefore the length of the hypotenuse is 14.14 inches.

How to find arc measurements
joja [24]
Finding an arc length requires knowing a bit about the geometry of a circle. Since the arc is a portion of the circumference, if you know what portion of 360 degrees the arc’s central angle is, you can easily find the length of the arc.

The slope of a line is -1/2. what is the slope of a line that is perpendicular to it.
weqwewe [10]
It is 2. You flip the fraction and make it negative always to get perpendicular slopes. If it was like 3, you treat it as 3/1 and would make it -1/3.
