I need help on the top ones and the bottom ones but they are 2 different ways of solving them, on the top ones you have to figure out if the angle is complementary or supplementary on the bottom, you have to write and solve an equation to find the measure of X in each figure and show the work for each step.

Titus works at a hotel. part of his job is to keep the complimentary pitcher of water at least half full and always with ice. when he starts his shift, the water level shows 4 gallons, or 128 cups of water. as the shift progresses, he records the level of the water every 10 minutes. after 2 hours, he uses a regression calculator to compute an equation for the decrease in water. his equation is w –0.414t + 129.549, where t is the number of minutes and w is the level of water. according to the equation, after about how many minutes would the water level be less than or equal to 64 cups?
