In ΔABC, \overline{AC} AC is extended through point C to point D, \text{m}\angle BCD = (9x-1)^{\circ}m∠BCD=(9x−1) ∘ , \text{m}\angle ABC = (3x+18)^{\circ}m∠ABC=(3x+18) ∘ , and \text{m}\angle CAB = (3x-4)^{\circ}m∠CAB=(3x−4) ∘ . Find \text{m}\angle CAB. m∠CAB.

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
