Answer:
x=23
Step-by-step explanation:
The first triangle has two sides that are the same, therefore the two bottom angles are the same as well, so the two bottom angles equal to 56 degrees of the total 180 degrees that a triangle should have. That leaves the last angle to be 124 degrees.
Now what you do is subtract 9 from 124 to get 115
Lastly divide 115 by 5 to get 23.

You need 270 cookies for 90 students.
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
