Using pythagorean theorem find a, and b, where a is twice of b and the hypotonuse is 5√5

patriot [66]

Measure of Hypotaneous = 5√5

And it's already given that b = 2a

By using pythagoras theorem:

a²+ b² = (5√5)²

Let's substitute for b as 2a in above equation we'll get:

a² + (2a)² = (5√5)²

a² + 4a² = 125
5a² = 125
a² = 25
a = √25 = 5

Therefore,
a= 5
and
b = 2a = 2(5) = 10.

Explain how to find the deviation of an entry in a data set

Ilia_Sergeevich [38]

The answer is: Find the mean of the differences with the other numbers in the set. Add the squared differences and then divide the total by the number of items in data in your set; take the square root of this mean of differences to find the standard deviation.

Diagonal = ?
Wide = 20 in.
High = 15 in.

Pythagoras formula: D² = H² + W²

$D^2=(15)^2+(20)^2\\ \\D^2=225+400\\ \\D^2=625\\ \\D= \sqrt{625}\\ \\D=25\ in.\quad\Longrightarrow\boxed{\boxed{\mathbb{ANSWER\ \checkmark}}}\\ \\ \\\textbf{HOPE\ THIS\ HELPS...!!}$
