The temperature at which water starts to boil is also linearly related to barometric pressure. water boils at 212 degrees f at a pressure of 29.9 inhg (inches of mercury) and at 191 degrees f at a pressure of 28.4 inhg.
a) find a relationship of the form t=mx+b, where t is degrees f and x is pressure in inches of mercury
b) find the boiling point at a pressure of 31 in hg
c) find the pressure if the boiling point is 199 degrees f
d) graph t and illustrate the answers to (b) and (c) on the graph

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
