Answer:
Step-by-step explanation:
A) identical triangles PSR and PSQ
B) in the given triangle PQR angle P is 90 degrees and PS is perpendicular on QR. so the angle PSR and angle PSQ is 90 degrees also angles RPS , SPQ are 45 degrees . hence when two angles of a triangle are 90 and 45 degrees. the third is also 45 degrees. when the three angles of two triangles are equal they are said to be similar
C) the triangle PSR is a isosceles triangle therfore the two sides of the two oposite equal angles must be equal. if RS=4 then SP=4 as well the sides opposite to 45 degrees angles. the third side can be found by using the formula
c²=a²+b²
c²=4²+4²=16+16=32
c=√32=√16*2=4√2
Answer:
37.5 minutes
Step-by-step explanation:
48/12 = 4 (for every 1 minute, 4 minutes of movie is downloaded.
change 2.5 hours to minutes = 60+60+30 = 150 minutes
150/4 = 37.5 minutes to download the 2.5 hour movie
Answer:

Step-by-step explanation:








Therefore, the angles that satisfy the equation are 
The slope of a line with points (8, 42) and (3, 25) is -17/5
<h3>The first step in graphing data in a scatter plot</h3>
To graph a scatter plot, we simply determine the axis to plot each of the corresponding data
The axes are simply x and y axes
Hence, the first step in graphing data in a scatter plot is (d) Determine which axis corresponds to which data.
<h3>The slope of the line</h3>
The points are given as:
(8, 42) and (3, 25)
The slope of the line is calculated as:
m = (y2 - y1)/(x2 - x1)
This gives
m = (25 - 42)/(3 - 8)
Evaluate
m = -17/5
Hence, the slope of a line with points (8, 42) and (3, 25) is -17/5
