I have a hypotenuse (side c) of 144

write an equation using pythagorean theorem to determine sides a & b using a right angle triangle assuming a=b.
Is that figureoutable only having the hypotenuse?

Yes because you told us it is a right triangle
Sin 45 = a/144
Cos 45 = b/144

2a^2=144^2
You solve.
Given a & b are equal.

We don't know it's an isosceles baw

I hate math

I have an X,Y location and have to figure out footage calls. That's easy at N, S, E & W.
I need the formula to do NE, SE, SW & NW.

The equation is a^2 + b^2 = 144.
a=b, so 2(a^2)=144.
ETA, misread and assumed the hypotenuse was 12.

Basically I know the spot I'm looking for is 144' dead NE from my x,y location.
I need to know how many feet E and then how many feet N from my X,Y to arrive at the point 144' away.

You didn't square c...

Nope. The equation is a^2 + b^2 = 144^2.

101.82 E, 101.82 N
Several ways to get there...

101.82 feet north, 101.82 feet east.

Yeah, when I saw 144 I just jumped to the assumption the hypotenuse was 12.

Geometry sucks. I like algebra and calculus better.
