1 answer:
The measure of angle ∠ACB is 70°. Then the correct option is C.
<h3>What is the triangle?</h3>A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
∠ABC + ∠BCA + ∠CAB = 180°
60° + ∠BCA + 50° = 180°
∠BCA = 180° – 110°
∠BCA = 70°
Then the correct option is C.
The complete question is given below.

Answer:
The population of this city in 13 years is 440,550.
Step-by-step explanation:
Given:
Suppose a city with population 300, 000 has been growing at a rate of 3% per year.
Now, to find the population of this city in 13 years.
Let the population of this city in 13 years be
Population () = 300,000.
Rate per year () = 3%.
Time () = 13 years.
Now, we put formula to get the population of the city in 13 years:
Therefore, the population of this city in 13 years is 440,550.
Answer:
20 mph and 4 mph
Step-by-step explanation:
GIVEN: A boat travels upstream for miles in
hours and returns in
hours traveling downstream in a river.
TO FIND: What is the rate of the boat in still water and the rate of the current.
SOLUTION:
Let the speed of boat in still water be and speed of current be
.
speed of water in upstream
speed of water in downstream
As
Solving both we get
Hence speed of boat in still water and rate of current is 20mph and 4mph respectively.
