K= -3

3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6

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

15. In the drawing, find the perimeter of triangle BIS.<br>

Nesterboy [21]

Answer:

29.86 units

Step-by-step explanation:

In the triangle BIS, IT is the bisector of angle BIS,

$BI \cong ST.... (given) \\$

Let BI = ST = x... (1)

By angle bisector property of a triangle, we have:

$\frac{BI}{IS} = \frac{BT}{ST}.... (2)\\\\\frac{x}{12} = \frac{4}{x}\\\\x\times x = 12\times 4\\\\x^2 = 48\\\\x=\sqrt{48}\\\\x = 6.92820323\\\\x = 6.93\\$

Therefore,

BI = ST =6.93

Perimeter of triangle BIS

= BI + IS + ST + BT

= 6.93 + 12 + 6.93 + 4

= 29.86 units
