Strip^2 = 65^2 + 72^2 = 9409
Strip = squareroot 9409 = 97 ft
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:

And we are told their difference is 36. Therefore:

Solve for the system of equations. Add b to both sides in the second equation:

Substitute this into the first:

Combine like terms;

Subtract 36:

Divide by 2:

So, b is 27 degrees.
Use the second equation again:

Now that we know b is 27, substitute:

Add 27 to both sides:

So, a is 63 degrees.
And we're done :)
We know that the three angles of a triangle always add up to 180.
Therefore, we have the equation:
55+20+x=180.
Solving for x, we get x=105.
