The measure of one angle of a right angle is 50 more then the measure of the smallest angle
Nataly_w [17]

Answer:

70° and 20°

Step-by-step explanation:

let x be the measure of one angle then x + 50 is the measure of the other angle, thus

x + 50 + x = 90

2x + 50 = 90 ( subtract 50 from both sides )

2x = 40 ( divide both sides by 2 )

x = 20

The smallest angle is 20° and the other angle is 20 + 50 = 70°

Determine the line described by the given point and slope (0,0) and 2/3
AlekseyPX

Answer:

The  line is  y=\frac{2}{3} x.

Step-by-step explanation:

Given:

Point and slope (0,0) and 2/3.

Now, to determine the line.

Here the point is:

(x_{1},y_{1}) =(0,0)

And the slope is:

m=\frac{2}{3}

Now, putting the formula and substituting the value from above to determine the line:

y-y_{1} = m(x-x_{1})

y-0=\frac{2}{3}(x-0)

y=\frac{2}{3} x

Therefore, the  line is y=\frac{2}{3} x.
