Answer:
= 8 mp /h
Step-by-step explanation:
Average speed=total distance/total time
=20/2.5
=8 mp/h
The sine ratio of angle θ is 4/5 because sin is the ratio to opposite to the hypotenuse.
<h3>What is a right-angle triangle?</h3>
It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right angle triangle showing in a picture.
As we know, the sin is the ratio to opposite to the hypotenuse.
Sinθ = 4/5
Thus, the sine ratio of angle θ is 4/5 because sin is the ratio to opposite to the hypotenuse.

Answer:
y=-2/3x +1
Slope = The change in y over the change in x so to do this you can use the two points To find the change in y to be -1-3=4 And the change in x to be 3 -(-3)=6 so you get -4/6 which can be simplified to -2/3 Then to find the next part find the y intercept which is y=1 at x=0
Answer:
60degrees
Step-by-step explanation:
For similar triangles, the angles of their angles are equal to matter the size.
Hence if triangle TRS is similar to triangle TMN, then;
<R = <M and <S = <N
Given that;
<T = 40 degrees
<R = 60degrees
<S = 80 degrees
Since <R = <M, then <M = 60degrees
