It is already in a decimal
I think you mean percent, so it will be 90%
Sorry if that is not what you mean
We can solve this by using the P<span>ythagorean theorem which is below:

Or we can say
</span>

<span>w = widht
h = height
d = diagonal measure
With that said, we know the height is .75 times the width so .75w. We also know d = 34, which is our diagonal measure.
w = don't know yet but need to find
h = .75w
d = 34
Now lets plugin the information we know into our equation</span>

Now lets to the math

Combine like terms
Divide both sides of the equal sign by 1.5625
Now take the square root on both sides of the equal sign

So the width is 27.2
We can check this by putting 27.2 back into our original equation

False because the factor tree for 61 is 1 and 61
There is no problem on here
The answer is B.55.8. Hope this helps!!
