Answer:
it looks hard
Step-by-step explanation:
OA ⊥ OC
Therefore, m∠AOC = 90°
m∠AOC = m∠AOB + m∠BOC
m∠AOB + m∠BOC = 90
5x+8 + 6x - 6 = 90
11x + 2 = 90
11x = 90-2
11x = 88
x = 88/11
x = 8
m∠BOC = 6x - 6 = 6*8 - 6 = 48 - 6 = 42°
90 mallards
No. of ducks = 200
Mallards = 45%
45% of 200 = 45/100 × 200
=90
I did the whole graph myself so you can just couple it down lol ;)
