Answer:
x = 21
Step-by-step explanation:
Diagonal angles are equal to eachother, so 143 = 6x +17
143 = 6x + 17
Subtract 17 from both sides
126 = 6x
Divide by 6
21 = x
To check put x as 21
143 = 6(21) + 17
Mutiply 6 by 21
143 = 126 + 17
add 17
143 = 143
You can take 8,000 and times it by 0.03. your answer is 2,500
Angle B = Angle D and the sum of these two is 70. X must be 180-60 = 110 degrees.
<u>Answer:</u>
6800 will be the population after 128 years.
<u>Step-by-step explanation:</u>
times it doubles: 128 / 64 = 2 times
so increase in population = 1700 * 2 * 2 = 6800 people.
