Answer:
3
Step-by-step explanation:
by question
5x+2=17
5×=15
×=3
For zeroes/roots r1,r2, r3
the facors of the polynomial is
(x-r1)(x-r2)(x-r3)
roots
-3,2,5
(x-(-3))(x-2)(x-5)
(x+3)(x-2)(x-5)
the coefient of the x term is -4
so mutliply the whole thing by 2
(2)(x+3)(x-2)(x-5)
expand
f(x)=2x^3-8x^2-22x+60
(2x+1)+89=180. 180 is the angle of a straight line. Set your two known sides equal to 180 and solve for x if needed.
