1) the formula for length of the hypotenuse of a triangle (short sides p and q) is r^2 = p^2 + q^2.
a) Making p the subject of the formula:
My answer: r^2 = p^2 + q^2 (p) = r^2 - q^2 = p^2 = final answer is: p^2 = r^2 q^2? is this correct?
b) what is the shortest side of this right angled triangle if the other two sides have lengths 9.3cm = q and 11.4cm = r ??
My answer: p^2 = r^2 - q^2 = 11.4 - 9.3 = final answer is: p^2 = 2.1cm??
I appreciate your help!

a. if you want it to be p= something
r^2=p^2+q^2
r^2-q^2=p^2
sqrt(r^2-q^2)=p there ya go
once again with b you are wrong you have to square those number,the numbers you have are the side length plug them in and you square them
9.3^2+11.4^2=r^2
86.49+132.02=218.51
then you have to square root r to find hyptoenuse which is 14.78
q would be the shortest
r^2=p^2+q^2
r^2-q^2=p^2
sqrt(r^2-q^2)=p there ya go

q would be the shortest

x^2+y^2=r^2
x, y - legs
r - hypotenuse
If you're making x the subject, you just plug in the hypotenuse and the other leg, and solve it algebraically -- you don't have to do anything beforehand.
b.)
9.3^2+y^2=11.4^2
43.47=y^2
6.59≈y
x, y - legs
r - hypotenuse
If you're making x the subject, you just plug in the hypotenuse and the other leg, and solve it algebraically -- you don't have to do anything beforehand.

9.3^2+y^2=11.4^2

Just need to square root that 2.1
