Thinking it was necessary for college, I took trig, analytical geometry and plane geometry in high school.
Never used any of them in college. I did take statistics which required fairly complex figuring.
I always thought plane geometry was the one which encouraged thinking.
Statistics involves algebra. Anything that has a variable value is automatically algebra. Where you have continuous random variables, that involves calculus.

I have a business degree, and a MBA and have never used Algebra in any manner in college. Nor have I used it in 5 decades after college.
Geometry was/is invaluable. I use it every day in driving, navigating a fishing boat, kayak, canoe and in the Navy to plot navigational courses. I use geometry in walking, back yard construction projects and inside household projects.
I had a lot of accounting hours in college.
What I learned in accting one is all that I needed in my 5+ decades of business life and personal life. We use CPA’s for our taxes.
The same experience with many hours of statistics. The first course has been very helpful everyday in business and real life. The other courses were a waste of time.
What you learn in basic economics and in particular basic supply and demand and their impact on price is probably enough for 99% of us.
Basic math, %’s and being able to budget business expenses and balance your personal checkbook are critical to surviving in our world not doing something you learned in Algebra.
Recognition of trends increasing or decreasing is helpful and critical in many aspects of life including investments.
Problem solving and being able to adapt to changes in the world and life are critical areas. This problem solving is dealing with humans and life events not with a straight line or curved approach or a mathematical theory. Those, who can only approach a problem with a certain mathematical process are often screwed when reality throws their straight line process into the garbage.
