Answer:
c
Step-by-step explanation:
Let x = total games played
16% = 0.16
0.16x = 40. Divide each number by 0.16.
x = 250
Wendy played 250 games
C.
You can factor that equation to the following:
x(x - 3)(x + 2)
Then set each part equal to zero and solve individually.
First
angle in front of c is 30°, so hypotenuse is equal to 2c
it's right triangle, so let's use Pythagorean theorem\

Second
b - the base of the triangle, angles at the base are equal ⇒ cathets are equal
it's right triangle, so let's use Pythagorean theorem
