Answer:
A=40, B=60, C=80
Step-by-step explanation:
180/7 to find what "1" would be in the ratio then multiply 20*2, 20*3, 20*4.
Since the total measure of all the angles of a triangle is always 180, solve for x with the equation: 3x+1+2x-3+9x=180. x=13. Now plug in x and look for the smallest one, which will be B. 23 degrees.
If f(x) is the inverse of g(x) then if f(a)=b then g(b)=a
so if G(s) is the inverse of S(g) then if G(2)=16 then S(16)=2, true
yes, it's true
