50?
I'm assuming 50 because the angles to a triangle always adds up to 180 and this one has 130 and 130+50=180
Answer:
13
Step-by-step explanation:
We know that a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
5^2 + 12^2 = c^2
25+144 = c^2
169 = c^2
Taking the square root of each side
sqrt(169) = sqrt(c^2)
13 =c
Interior angles of a square always sum to 360°. A reflection in the x-axis would not change this.
