Answer:
Population in 1950 was 4,100,000
Step-by-step explanation:
Equation: 5x + 2,000,000 = 22,500,000
Subtract 2,000,000 from each side: 5x = 20,500,000
Divide each side by 5: x = 4,100,000

Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.
The Angle Addition Postulate is gotten from angles placed side by side to form a resulting angle that is the sum of all the individual angles.
If D is the interior of ABC then, ABC is split into two parts i.e ABD and DBC, then the measure of ABC is the sum of the individual two parts
m∠ABC = m∠ABD + m∠DBC.
Using the Angle Addition Postulate:
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 15 + 40 = 55°
m∠ABC = 55°
2:5, 2/5, 2 to 5
Answer:x=4
68 degrees
Step-by-step
22 degrees +B=90 degrees
B=68
