19.6 is the answer to your question
109!!
180-64-45= 71. Angle x amd the interior angle create a 180 degree line. And 180-71= 109; the sum of the 2 angles in the triangle are equivalent to the exterior angle
You have to figure out the highest common factor of each set of values:
9a + 21 = 3(3a + 7)
21b - 49 = 7(3b - 7)
54 - 6c = 6(9 - c)
8a + 32b = 8(a + 4b)
4p + 28q + 8r = 4(p + 7q +2r)
84a - 36b -12c = 6(14a - 6b - 2c)
6p + 9q + 15r = 3(2p + 3q + 5r)
18s - 30t + 54u = 6(3s - 5t + 9u)
Hope this helps :)
All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).
Example: factors of 12
12 ÷1 = 12
12÷ 2 = 6
12÷3= 4
12÷4 = 3
12÷6=2
12÷12 = 1
= {12,6,4,3,2,1}
Composite Number/ Its Factors
4 = {1,2,4}
6 = {1,2,3,6}
8 = {1,2,4,8}
9 = {1,3,9}
10 = {1,2,5,10}
12 = {1,2,3,4,6,12}
14 = {1,2,7,14}
15 = {1,3,5,15}
16 = {1,2,4,8,16}
18 = {1,2,3,6,9,18}
20 = {1,2,4,5,10,20}
21 = {1,3,7,21}
22 = {1,2,11,22}
24 = {1,2,3,4,6,8,12,24}
25 = {1,5, 25}
Hope it helps!
