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

Sin x cos x = -cos x<br> Find all angles that satisfy the equation below
n200080 [17]

Answer:

x=90^\circ,270^\circ

Step-by-step explanation:

sinxcosx=-cosx

sinxcosx+cosx=0

cosx(sinx+1)=0

cosx=0

x=90,270

sinx+1=0

sinx=-1

x=270

Therefore, the angles that satisfy the equation are x=90^\circ,270^\circ

The first step in graphing data in a scatter plot is which of the following?
faust18 [17]

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
