Use the triangle at the right. Find the length of the missing side. Is this right??
1. a = 16, b = 63
a^2 + b^2 =c^2
162 + 632 = x2
256 + 3969 = x2
√4225 =√ x2

yes but the last one now u just it square it to get the final answer

thanx:)

phi · Answer

you don't show the triangle.  Just to be clear,  you did it correctly as long as the unknown side is the hypotenuse (which is the side opposite the 90 degree angle)
the final step is
sqr(4225)= x
or
x= 65

phi · Answer

that shows that "c" (the hypotenuse) is the unknown side (because they show that a and b are the "legs" )

so you did it correctly.  The final answer (use a calculator to simplify sqr(4225)) is c=65

yanasidlinskiy · Answer

a=16, b=63

ok:) thanx:) i thought so i did it correctly:)

i have another question...whats the square root of 91??

phi · Answer

9*9= 81
10*10= 100

91 is between 81 and 100
so sqr(91) is between 9 and 10

thanx:)i appreciate your help:)

phi · Answer

type 
sqrt(91)=
into google to get a decimal approximation
