1. Find m2K.

Mathematics
1 answer:
Kruka [31]3 years ago
5 0

Answer:

m∠k = 60°

Step-by-step explanation:

  • an exterior angle of a triangle is equal to the sum of the opposite interior angles

4x + 2 + 6x - 12 = 130

to find x:

4x + 2 + 6x - 12 = 130

4x + 6x = 130 - 2 + 12

10x = 120

x = 120/10

x = 12

apply the value of x to find the measure of angle K:

k = 6*12 - 12 = 60

Two sides of a triangle have lengths 11 and 18. Write an inequality to represent the possible lengths for the third side, x.
KatRina [158]
<span>Side inequality of triangle states that the sum of any two sides of a triangle should be greater than the third side so the sum of two sides

In this case, 11 + 18 = 29 > 3rd side So 29 > 3rd side or we can say 3rd side < 29

Also, the third side cannot be smaller than the difference of the given two sides so the third side has to be greater than 18-11 = 7 so 3rd side > 7 so if length of 3rd side is represented by x, then 7 < x < 29</span>

Answer:

  8, 16, 64

Step-by-step explanation:

  8 = 2^3 . . . a perfect cube

  16 = 4^2 . . . a perfect square

  32 = 2^5 . . . neither a cube nor a square

  64 = 2^6 = 4^3 = 8^2 . . . both a perfect cube and a perfect square

  128 = 2^7 . . . neither a cube nor a square

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
BlackZzzverrR [31]

Answer:

50

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50
