Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 =
(140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°
Answer:
5.18 pounds per square inch
Complete question:
If the pressure is 6 pounds per square inch when the temperature is 440° F,find the pressure exerted when the temperature of the gas is 380°F.
Step-by-step explanation:
According to the Gay Lussac's Law:
where, P and T are the pressure and temperature of an enclosed ideal gas.
Given:
Initial pressure = 6 pounds per square inch
Initial Temperature =440° F
Final Temperature =380° F
Final Pressure =?
Substituting all values in the formula
=
= 5.18pounds per square inch
