Answer:
x =55 degrees
y = 35 degrees
Step-by-step explanation:
We know that the distance from the center of the circle to the circumference is the radius
that means the triangle starting out from O is isosceles since two of the sides are radii and thus the angle of those sides are the same
Let us call one of the angles z
we know that the sum of the angles in a triangle is 180 degrees
That simply means;
80 + 2z = 180
2z = 180-80
2z = 100
z = 100/2
z = 50 degrees
So the angles at each upper end of the cyclic quadrilateral are;
x + 50 and y + 50
we know that the angles that face each other in a cyclic quadrilateral are supplementary
Thus;
95 + y+ 50 = 180
y= 180-95-50
y= 180-145
y = 35 degrees
Now, for x, the angle supplementary to the angle that faces x+ 50 equals x + 50
Thus;
x + 50 = 105
x= 105-50
x = 55 degrees
Answer: 30%
Step-by-step explanation:
First find the difference between the old score and the new:
= 390 - 300
= 90 points
To find the percentage increase, divide the difference by the original score:
= 90 / 300
= 30%

Answer:
22
Step-by-step explanation:
So, first, we can find out how many home runs the coach hits in one game
So, 18 home runs in 9 games, so we can do 18 ÷ 9=2
So, he hits 2 home runs per game
But, we have to find for 11 games
So, we do 2*11(Runs times number of games) and get 22
Hope this clarified
