∠A and ∠B\angle B ∠B are supplementary angles. If m ∠A=(x−18)∘\angle A=(x-18)^{\circ} ∠A=(x−18) ∘ and m ∠B=(x−20)∘\angle B=(x-20)^{\circ} ∠B=(x−20) ∘ , then find the measure of ∠B\angle B ∠B.

Given:

∠A and ∠B are supplementary angles.

m∠A=(x−18)° and m∠B=(x−20)°.

To find:

The measure of ∠B.

Solution:

Sum of supplementary angles is always 180 degrees.

∠A and ∠B are supplementary angles. So,

Now,

The measure of angle B is

Therefore, the measure of ∠B is 89°.

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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.
