Answer:
45
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
3x+5x+4x = 180
Combine like terms
12x = 180
Divide by 12
12x/12 =180/12
x = 15
The smallest angle is 3x
3(15) = 45
Slope: (y2-y1)/(x2-x1)
(-3-4)/(5-9) = -7/-4
The slope is 7/4
Multply across the fraction so
1/2 * 3/4= (1*3)/(2*4)=3\8

You can't solve this problem, only simplify it.</span></span></span></span>
