7 0

Answer:

1

Step-by-step explanation:

once we know 2 of the angles we can find a third. once we have all 3 angles we only need one side length to tell us how big it is.

Bonus question: How many triangles can be drawn with one 3 inch side ,a 4 inch side, and a  20ºangle?

Find the measure of unknown angle​
inna [77]

Answer:

a = 85° , b = 30° , c = 65°

Step-by-step explanation:

∠ a and 85° are alternate angles and are congruent , so

a = 85°

∠ c and 65° are alternate angles and are congruent , so

c = 65°

a, b and c lie on a straight line and sum to 180° , that is

a + b + c = 180°

85° + b + 65° = 180°

150° + b = 180° ( subtract 150° from both sides )

b = 30°

Find the average rate of change of k(x)=5x–19 over the interval [<br> -<br> 14,<br> -<br> 4].
rusak2 [61]
The rate of change of a function can be modeled with the following expression:

\frac{\Delta{k{x)}}{\Delta{x}}

Where Δx is the change in x value, and Δk(x) is the corresponding change in k(x). We're given the two extremes of x, so we can calculate the change in x to be

\Delta{x}=-4-(-14)=10

To find the change in k(x), we can calculate the values of k(x) at x = -14 and x = -4 and find the difference between them:

k(-14)=5(-14)-19=-70-19=-89\\ k(-4)=5(-4)-19=-20-19=-39\\ \Delta{y}=k(-14)-k(-4)=-89-(-39)=-50

So, the rate of change for the function from x = -14 to x = -4 is

\frac{\Delta{y}}{\Delta{x}}= \frac{-50}{10}=-5
