Answer:
x = 19
Step-by-step explanation:
x + (x + 4) + (3x - 9) = 90°
Combine like terms
5x - 5 = 90
Add 5 on both sides
5x = 95°
Divide 5 on both sides
x = 19
Answer: The size of sample of 193 is needed.
Step-by-step explanation:
Since we have given that
Margin of error = 6%
At 90% confidence level, z = 1.645
Let p = 0.5
and q = 0.5
( because it is the most conservative estimation).
So, using formula, we get :

Hence, the size of sample of 193 is needed.
