Answer:
We know that an isosceles triangle has 2 of its sides being equal
With R, being the midpoint of PS, we can say that
PR=RS
Noting that, with R as midpoint, we can conclude that RT is a straight line which divides angles TPR and TSR into 2 right angle triangles
Step-by-step explanation:
therefore angle at P is 45°. Angle at S also 45°
Therefore PT = TS
This is because T is 45 degrees as well as P which is also 45 degrees
angle in triangle PTS is 180 degrees
R is 90 degrees, P is 45 degrees and the whole of T is also 45 degrees(which has been split into 2)
Answer:
Step-by-step explanation:
Let the required volume be x
<u>Use the ratio of gallon/volume to solve:</u>
- 1/0.13 = 20/x
- x = 20*0.13
- x = 2.6 ft³
With 20 gallons the scientist can cover 2.6 ft³ of water volume
