Planes x and y intersect at a right angle. line a b and line c g lie in plane x and do not intersect. line r s lies in plane y.

How can we find the measure of an exterior angle if we know the measurement of an interior angle

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

Can (3,5 and square root 34) be sides on a right triangle?
