Answer:

angle 1 = 3x = 27

angle 2 = 5x = 45

angle 3 = 12x = 108

Step-by-step explanation:

12x + 5x + 3x = 180 ......... (angle sum property)

20x = 180

x = 180/20 = 9

angle 1 = 3x = 27

angle 2 = 5x = 45

angle 3 = 12x = 108

I hope im right!!

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (3, 2); m = 2/3

77julia77 [94]

Answer:

$y - 2 = \frac{2}{3}(x-3)$

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Slope: $\frac{2}{3}$

Point: (3, 2) = (x1, y1)

To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:

y - y1 = m(x - x1)

$y - 2 = \frac{2}{3}(x-3)$

The equation in point-slope form is: $y - 2 = \frac{2}{3}(x-3)$
