Answer:
A.111.11 repeating
B.25.85
Step-by-step explanation:
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
Answer:
A
Step-by-step explanation:
If it’s 80 less than, your subtracting and then 4 times a number is 4x so your answer is 4x-80
A=1/2ap
(40ft^2)=1/2*8*p
p=(40ft^2)/4
