2nd spring break blog

okay so today is last day of spring break which means last blog of spring break. today im going over chapter 9 which is triangles. ill be focusing on section 1 which is solving right triangles. to find sin of a right triangle you do opposite / hyptoenuse. to find cos you do adjacent / hypotneuse. to find tan you do opposite / adjacent. this is referring to the angle and the legs. whatever angle you are using you find sin cos or tan with the legs. the examples will explain this better below.


EX: in triangle ABC, angle A = 90 angle B = 25 and a= 18. find b and c
from this information you know angle C = 65 so now you can work the problem
first thing to do is solve for b or c first so lets go with b
