x^2 + 21^2 = 29^2

x^2 + 441 = 841

x^2 = 841 - 441

x^2 = 400

x = √400

x = 20

Andy is one fourth as old as his grandfather who is 76 years old write an equation to determine whether Andy is 19 or 22 years o
iren [92.7K]
76÷4= ; x=19, you divide 76 by 4 because if he is 1/4 then it would be a group of one of the 4's, thus saying ehen you divide 76 by 4, it equals 19, so he is 19 years old, you could also do 19×4 and 22×4 to see which equals 76.

Special right triangles: Find the missing side length <br> Show work
Gnesinka [82]

Answer:

This is a 45-45-90 right triangle

So we know that because at least one angle is 45 degrees and there is a right angle.

A 45-45-90 triangle has congruent (equal) legs {x} and the hypotnuse is

x√2

So using that information we know X = Y

Since they are both legs and legs are congruent in this case.
The hypotnuse is laid out for us which is 8.

We can make an equation.
Since the hypotnuse would be x√2

x√2 = 8

Now we solve.

You’d get 5.6528… or √32

X and Y both equal √32
