  A: 1; B: 3; C: 2; D: 2; E: 4

Step-by-step explanation:

The sum of angles in a triangle is 180°. This statement is called the "Triangle Sum Theorem."

Statement line 2 is a list of the three angles in the triangle. The one missing is angle S (tile 1, answer A). The missing theorem description is tile 3, answer B.

Statement lines 3 and 4 are algebra. Line 3 is a substitution of a number for the measure of angle Q. Since angle Q is marked as a right angle, its measure is 90° (tile 2, answer C). Line 4 subtracts that 90° from both sides of the equation, resulting in a statement that the sum of the two angles is 90° (tile 2, answer D).

Finally, we declare the angles complementary because we've shown their sum is 90°. That's a matter of definition. (tile 4, answer E).

9 x 8 divided by (5-3)=36

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
