Task 4: Stellar Distances Rigl Kent is a man sequence star (G2) Its temperature is measured to be about 5 800 K If
the apparent magnitude is +1 33 then how far is it from the Earth?
Hint use the Hertzsprung-Russell diagram to find the absolute magnitude of a star with such
characteristics

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle. he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field

If value of cos330° is √3/2 then find tan165°.
