The equation to find the right triangle is a^2+b^2=c^2 or the Pythagorean Theorem.
a^2+b^2=c^2 Substitute the values
18^2+26^2=c^2 Solve the powers
324+676=c^2 Simplify
1000=c^2 Solve the the square
31.6=c

start at -2 go over 2 and up 5
(-2, 5)
93+36+m=180 combine like terms
93+36=129 rewrite
129+m=180 subtract 129 from both sides
180-129=51 rewrite
M=51 and to check this just plug 51 in for m
93+36+51=180
93+36=129
129+51=180
180=180
Hope this helps have a nice nite!
