Question

How do I solve a problem like this??

Answer 1

Well this is an equilateral triangle so then a=b. so then b=4 as well. so then now you have a^2 + b^2=c^2.

4^2+4^2=c^2

16+16=c^2

32=c^2

Find the square root of 32 which is approximately 5.65685.

Find the square root of c^2 which is c.

so then 5.65685=c
