Answer:
y= ¼x
Step-by-step explanation:
<u>Slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept.

Slope



Substitute the value of the slope into the equation:
y= ¼x +c
To find the value of c, substitute a pair of coordinates.
When x= 12, y= 3,

3= 3 +c
c= 3 -3
c= 0
Thus, the equation of the line is y= ¼x.
The sum of the three angles of a triangle is always 180 degrees. If the triangle is right, which means one of the angles measures 90 degrees, the other two angles should add up to 90 degrees. With this condition and the given above, x + 15 + 2x = 90. Solving for x in the equation gives x = 25. Substituting x to the given expression for the acute angles gives the measurements of 40 and 50 degrees. Thus, the smallest angle of the triangle is <em>40 degrees</em>.
