What is the measure of b in the triangle?

this triangle is not drawn to scale

70°

Step-by-step explanation:

(a) Calculate the value of x

∠A +   ∠B     +   ∠C    = 180

40 + 2x - 30 + x + 20 = 180

Combine like terms

3x + 30 = 180

Subtract 30 from each side

3x = 150

Divide each side by 3

x = 50

(b) Calculate m∠B

m∠B = 2x - 30 = 2×50 - 30 = 100 - 30 = 70°

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
