So first you make two isosceles triangles, one is URS and the other is UST. First find the degrees of angle RSU which is (180-120)/2=30. Then you know that TSU is 70 and then you can find angle T is 180-70*2 which is 40.
Another method, which is faster is that in a quadrilateral, all angles make 180 degrees. 120+100+100 is 320 and 360-320 is 40.
Answer:
625
Step-by-step explanation:
Answer:
The final volume is 320 mL at pressure of 100 kPa.
Step-by-step explanation:
Boyle's law gives the relation between volume and pressure of a gas. It states that at constant temperature, volume is inversely proportional to its pressure such that,
Let
We need to find . Using above equation, we get :
So, the final volume is 320 mL at pressure of 100 kPa.
