Question

I just got switched into a new geometry class and I don't understand anything. Please help me.

Answer 1

I attached the problem

Answer 2

These 3 questions all involve Pythagoras' Theorem

\[c^2 = a^2 + b^2\]

so in the 1st question you have

\[50^2 = (2x)^2 + (x)^2\]

square both terms on the right and you get

\[2500 = 4x^2 + x^2\]

now you can collect like terms and solve for x.

the other questions work in the same way.

In all 3 questions, the given measurement is on hypotenuse.

hope it helps
