Answer:
15.
16. m<V = 103°
17.
Step-by-step explanation:
15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°
Therefore:
Solve for x
Add like terms
Subtract 112 from each side
Divide both sides by 31
16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:
Solve for x
Add like terms
Subtract 321 from each side
Divide both sides by 21
m<V = 5x + 8
Plug in the value of x
m<V = 5(19) + 8 = 95 + 8
m<V = 103
17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.
Therefore:
Solve for x
Add 18 to both sides
Divide both sides by 9
Answer:
Step-by-step explanation:
We can either look at all 62 characters (2 * 26 in the alphabet and 10 digits), choose 6 of them, and add the fact that we care about their order - so multiply by 6! and we get
Or, we can look atr all the permutations of all the characters and take into account that we DON'T care about the order of the 56 after the first six. Getting immediately.
