Answer:
x = 0
x = 3
Step-by-step explanation:
Let's say "n" is a natural number. {1,2,3,4,..} To ensure we have an even number we will multiply "n" by 2. Two times any number will make an even number.
consecutive even numbers are like; 2, 4, 6, 8, 10 .. etc. Add +2 to the previous number to get the next consecutive.
1st even number = 2n
2nd even number = 2n + 2
3rd even number = 2n + 4
twice the first number (2n) is 20 more then the second (2n + 2).
2(2n) = 2n + 2 + 20
4n = 2n + 22
4n - 2n = 22
2n = 22
n = 11
Now use n = 11 to find the 3 consecutive even numbers.
1st even number = 2(11) = 22
2nd even number = 2(11) + 2 = 24
3rd even number = 2(11) + 4 = 26
22, 24, 26
Answer:
Step-by-step explanation:
Pretty Tall.
Tan(72) = opposite / adjacent
The opposite is the height of the building
The adjacent = 100
Tan 72 = 3.077
Tan (72) = opposite / 100
3.077 = opposite / 100 Multiply by 100
3.077 * 100 = opposite
opposite = 307.7
opposite rounded = 308
