Since this is a right triangle the two acute angles must sum to 90 degrees because a triangle's angles must sum to 180 degrees.
2x+50+3x=90
5x+50=90
5x=40
x=8
So the smallest angle is 3x=3*8=24°
Answer:
it should be somewhere along the lines of 2.25
Step-by-step explanation:
Answer:
y=-0.012x(x-200).
Step-by-step explanation:
1) the given parabola has two zeros: 0 and 200. It means, the required equation is: y=ax(x-200), where a - unknown number;
2) according to the given graph the vertex is (100; 120). It is possible to substitute the coordinates of it into the equation y=ax(x-200) and calculate the value of 'a':
120=a*100(100-200); ⇒ a=-0.012.
3) finally, the required equation is:
