Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

\frac{3x}{3} = \frac{60}{3}

x = 20

What is the equation of (0,2) and (3,0)
ivolga24 [154]
Let's first find the slope. This is (y_2 - y_1)/(x_2 - x_1), where (x_1, y_1) and (x_2, y_2) are points.

For this problem, our slope is (0 - 2)/(3 - 0) = -2/3.

We can now use the point-slope formula to find the equation of our line:
(y - y_1) = m(x - x_1)
(y - 2) = -2/3(x - 0)
y - 2 = (-2/3)x
y = (-2/3)x + 2

The equation of our line is \boxed{y = -\frac{2}{3}x + 2}.
