Mathematics
1 answer:
Firdavs [7]3 years ago
8 0

Step-by-step explanation:

DC is equal to 180°, so subtract 105 from 180.

180-105=75

180 is the total of the the angles when added together.

67°+75°=142

180-142=38

x=38

Answer:

y = 10/3x + 20

Step-by-step explanation:

First, we need to find the slope of the function. We can do that by using two points and inserting them into the slope formula. It can be any two but I'll just pick (3, 30) and (6, 40).

m = y₁ - y₂ / x₁ - x₂

m = 30 - 40 / 3 - 6

m = -10/-3

m = 10/3

Now we know the slope is 10/3.

In slope-intercept form, the y-intercept is the constant at the end of the equation. The table of values tells us that the y-intercept is located at (0, 20). So the equation of the linear function is y = 10/3x + 20.
