Find the measurement of ∠b.

m∠b +
° +
° =180°

m∠b =
°

Step-by-step explanation:

We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°

We can solve for (a) by subtracting 120 from 180, which is 60.

180-120=60

m∠a+120°=180°

m∠a=60°

We know that the sum of all angles in a triangle is 180°.

Therefore, (a)+60°+(b)=180°

We know that (a) is equal to 60°, so our new equation is:

60°+60°+b=180°

60+60=120

180-120=60

m∠b+60°+60°=180°

m∠b=60°

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
