Answer:
A: 5
Step-by-step explanation:
Rise over run is 3 over 4. Using the pathagorean thereom, you can calculate using the equation a^{2}+b^{2}=c^{2}.
Plug in (3)^2 + (4)^2 = the square root of 25
x = 116º
the sum of angles on the same side equals 180º so:
x + 64º = 180º subtract 64º from both sides
