Answer:
x = 60
Step-by-step explanation:
The sum of the angles in a triangle is 180
40 + x+20 + x = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x+60-60 =180-60
2x =120
Divide by 2
2x/2 =120/2
x = 60
At this case it could be calculated like this: 7+5*20=107

Answer: 17604
Explanation: In order to find a percentage, mulptiply the population by the percentage with a decimal in front. Like this:
32600 • .46

32600 - 14996 = 17604
You're done! Hope this helps
