That is a right triangle. So I think it’s a2+b2=c2. So it will be 7 the power of 2 plus the 10 the power of 2. So, it will be 49 plus 100, and that will be 149. Then it’s gonna be c2=149. How you gonna remove the 2, using square root. So square root of 149 is 12.2. So your final answer is 12.2. Check the calculator if I am right.
