The value of x is 10
Step-by-step explanation:
We know that the sum of internal angles of a quadrilateral is 360 degrees
So,
Given
Angle 1 = A1 = 3x+10
Angle 2 = A2 = 9x+50
Angle 3 = A3 = 4x
Angle 4 = A4 = 13x+10
So,

Subtracting 70 from both sides

Dividing both sides by 29

Hence,
The value of x is 10

Yea i think it is the first one
Step-by-step explanation:
Answer:
209 points
Step-by-step explanation:
Mean points scored (μ) = 182 points
Standard deviation (σ) = 14 points
The z-score for any given game score 'X' is defined as:
At, the 97th percentile of a normal distribution, the z-score, according to a z-score table, is 1.881.
Therefore, the minimum score, X, needed for a bowler to receive a trophy is:

Since only whole point scores are possible, X=209 points.
