Answer:
A = 65deg
B = 78deg
Step-by-step explanation:
It's a triangle, so we know that the sum of angles is 180deg
x + (2x - 9) + (2x + 4) = 180
5x - 5 = 180
5x = 185
x = 37
Measure of angle A = (2*37 - 9)deg = 65deg
Measure of angle B = (2*37 + 4)deg = 78deg
Answer:
The answer is A) stemplot
I will find comission
7% of 210000
percent means parts out of 100
7%=7/100
7/100 times 210000=1470000/100=14700
comission is $147000
Ok, find change then divide by years elapsed
change=310-280 million=30 million
number of years elapsed=10
30mil/10=3mil
3million per year was the population growth rate
31500 meters.
Step-by-step explanation:
3.5 km times 9 = 31.5 km
25.5 km = 31500 meters
