Answer: 5870 rounded to the nearest thousand is 6000
Step-by-step explanation:
Remember, when we round we have to be careful with the place value they are asking you to round to. Here, they want you to round to the thousands place. So, you have to look at the hundreds.
5870. 800 is the hundreds, and it is greater than “5”. So, you round to the next thousands. It happens to be 6000.
<em>Hence, 5870 rounded is 6000.</em>
I am pretty sure it's the second sentence.
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
∴
In the diagram, and
m∠A=60° and m∠C=45°
∴
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
From the diagram,
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
=
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
