Find the length of the missing side of the right triangle, 13 yd
Syd
A. 194 yd
B 13.93 yd
C. 144 ya
D. 12 yd

12

Step-by-step explanation:

For these problems you should use the pythagorean theorem: a^2+b^2=c^2

In this case, 13=c and 5=a

so:

5^2+x^2=13^2

25+x^2=169

subtract 25 from both sides

x^2=144

√144=12

missing side=12

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
