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 th
pantera1 [17]

Answer:

B) { 51, 149, 140 }

C) { 16, 63, 65 }

Step-by-step explanation:

We need to choose Pythagoras theorem formula

c^2=a^2+b^2

now, we can verify each options

option-A:

a=1

b=1

c=1

now, we can verify formula

1^2=1^2+1^2

1=2

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

149^2=51^2+140^2

22201=22201

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

65^2=16^2+63^2

4225=4225

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

11^2=6^2+8^2

121=100

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

so, this is FALSE

The circle is inscribed in Triangle AEC. Which are congruent line segments
Harlamova29_29 [7]

Answer:

E-F and E-D

C-B and C-D

Step-by-step explanation:

The circle and triangle are as shown.  The options are:

  • A-B and C-B
  • E-F and E-D
  • E-D and C-D
  • A-F and E-F
  • C-B and C-D

By drawing radius lines from the center of the circle to the tangent points B, D, and F, we can divide the triangle into 3 kites.  Therefore, only segments that are legs of the same kite are congruent.  So the answer must be E-F and E-D, and C-B and C-D.

Find two numbers whose difference is 154 and whose product is a minimum.
Serggg [28]
Y - x = 154
let z = xy = x(154 + x) = x^2 + 154x

we need to find the minimum value of z

z' =   2x + 154  which = zero for minm or maxm value

x = -77   and y = 154 -77 = 77

so the 2 numbers are -77 and 77
