Find the measure of the numbered angle.
m∠8 =

∠ 8 = 140°

Step-by-step explanation:

∠ 8 and 40° are adjacent angles and supplementary ( sum to 180° ), then

∠ 8 = 180° - 40° = 140°

m∠8 = 140°

Step-by-step explanation:

40 and angle 8 are supplementary angles

this means they add up to 180°

so, you can make the following equation:

40 + m∠8 = 180

subtract 40 from both sides of the equation

40 - 40 m∠8 = 180 - 40

m∠8 = 180 - 40

m∠8 = 140

sine

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
