Answer:

Step-by-step explanation:
θ = 228° = (228°)×(π/180° radians/degree) = 228/180 radians
= 19/15 radians
≈ 1.266...(repeating) radians
Answer:

Explanation:
Let's begin writing down everything
(X×(-11)+5)×(-9)+X-55
Now we can multiply
-9(-11X+5)+X-55
99X-45+X-55
And so we get
100X-100
Factorize 100
100(x-1)
