Find an equation of the line described (3,7) (0,0)

Colt1911 [192]

The formula of the line is
y=mx + b
The likes goes through the point (0,0)
that means that y-int = 0, b=0
y=mx
So we need to find only slope.

$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{7-0}{3-0} = \frac{7}{3} 

$

$So, y= \frac{7}{3} x$

Find the value of x then classify the triangle by its angles

Neporo4naja [7]

Answer:

Step-by-step explanation:

3x + x + 60 = 180.

first, we add the x's together.

4x + 60 = 180

then we see if they all have a common multiple. in this case, they do. they are all divisible by 4, so we can use that.

x + 15 = 45

then, just subtract 15 from both sides, that way we get the variable by itself.

x = 30

also, it is a right triangle. the top angle (3x) multiplied by 3 is 90. any triangle that has a 90 degree angle is automatically a right triangle.
