If we apply the pythagorean theorem to the egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 . which of the sets of three numbers listed would also let you form a right angle in this way? choose all answers that apply: choose all the answers that apply : a) { 1,1,1 } b) { 51, 149, 140 } c) { 16, 63, 65 } d) { 6, 11, 8 }

Its B and C

Step-by-step explanation:

TRUST ME !

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

We can see that left side is not equal to right side

so, this is FALSE

option-B

a=51

b=140

c=149

now, we can verify formula

We can see that left side is  equal to right side

so, this is TRUE

option-C

a=16

b=63

c=65

now, we can verify formula

We can see that left side is  equal to right side

so, this is TRUE

option-D:

a=6

b=8

c=11

now, we can verify formula

We can see that left side is not  equal to right side

so, this is FALSE

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
