The triangle angle-sum theorem says that all those angles added together equal 180. Therefore, 120+x+x+16=180 and 2x+136=180 and 2x=44. Therefore, x = 22, which is angle B.
Answer:
coefficient of x^2 is -4
and degree of polynomial is 3
4-3i is the complex conjugate
28 each book 155-15=140 and then 140÷5=28
Well the y-intercept is +2
And the slope of the blue line is 1/2
So y=1/2x+2
Slope is rise/run (up then ((right)))
And the intercept is found where the line intercects the y line.
