Using the distributive property , 4*9+4*7 or 36+28
Answer: See below
Step-by-step explanation:
The Pythagorean Theorem is a²+b²=c². Since each problem gives us the length of a, b, or c, we can directly plug them into this equation and solve.
Triangle EFG
9²+b²=41²
81+b²=1681
b²=1600
b=√1600
b=40

Triangle PQR
20²+21²=c²
400+441=c²
c²=841
c=√841
c=29

Triangle XYZ
a²+24²=25²
a²+576=625
a²=49
a=√49
a=7
