Step 1:
Set Variables (We will use x & y)
x = years
y = total orangutan population
Step 2:
Set up Equations
784 - 25x = y
817 - 36x = y
Step 3:
Set equations equal to each other & solve
784 - 25x = 817 - 36x
784 = 817 - 11x
-33 = -11x
3 years = x
C because u can split it only once vertically but it’s not a rotationally symmetrical shape
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
