Can someone help in Geometry?

Find the specific measure below

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

What is the measure of angle 1? a.28 b.152 c.168 d.64

How do you find p(a and b) if a and b are independent events for two or more actions, such as tossing a coin twice and finding p(heads and heads)? 2. how do you find p(a or b) if a and b are independent events for one action, such as spinning a four-color spinner once and finding p(red or blue)?
