Answer:
1) 13m, 2) 10ft, 3) 11.4ft, 4) 12.7m
Explanation:
Since all of these triangles are right triangles, we can use the Pythagorean Theorem: a^2+b^2 = c^2
1) 5^2+12^2 = c^2 = 25+144 = c^2 = 169 = c^2 = 13 = c
2) 6^2+8^2 = c^2 = 36+64 = c^2 = 100 = c^2 = 10 = c
3) 5^2+10.3^2 = c^2 = 25+106.09 = c^2 = 131.09 = c^2 = 11.4494541 = 11.4 = c
4) 8.6^2+9.4^2 = c^2 = 73.96+88.36 = c^2 = 162.32 = c^2 = 12.7404866 = 12.7 = c
