Triangle ABC is similar to triangle XZY. Find the missing side x using proportions ( PLEASEE HELP ASAP)

x=70º

Step-by-step explanation:

Triangle ABC, A/C=50º, B/C=40º

40º+50º=90º

Triangle XZY, Y/Z=20, Y/X=x

Since it is a right triangle it will add up to 90º.

So 90º-20=70

The missing angle x is 70

x= 70

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
