Can someone explain to me how to do

A straight line is 180°, so you can do this:

118 + y = 180

y = 62°

The triangle is an isosceles triangle, so the other angle of the triangle is 62° too.

Now that you have 2 of the 3 angles, you can go find the 3rd angle.

62 + 62 + z = 180

z = 56°

Now you can go find ∠2

56 + ∠2 = 180

∠2 = 124°

124 = 12x + 4

120 = 12x

10 = x

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

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.

hope i !
