To become a chemist you need a wide range of talents, but the main types of math that they use are probobly Algebra, trig, and Calculus.

trig
Much of what is done in the lab involves chemistry or preparation of standard solutions at different concentrations. Chemistry, well all sciences really, involve math. Chemistry in the lab involve simple math calculations. Algebra, trig, and calculus are used to analyze data
Yes, sine is a trig function, it is opposite over hypotenuse.
Trig
Yes, trig is the math of triangles, particularly right trianges.
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.
Trig identities are vital in upper level math. Anything involving the unit circle or triangles is completely based in the trig identities. Trig is used in many other fields, such as architecture, where the identities play a huge role.
some algebra, mostly geometry, and a little bit of trig.
Basic arithmetic, plane geometry and trig ought to do it.
Tenth grade math varies since it is in high school and there are different types of classes. It can be Geometry, Algebra, or Trig normally.

Geometry is a prerequisite for trigonometry. Trig is a prerequisite for higher math, which is going to be used throughout your life.

It comes from "Trigonometry." Tri: Three Gon: Side Ometry: Study
I am a retired math/science teacher. I used trig every day to teach students.
