As Given ,
Members play football and basketball = 20
Members play football and vallyboll = 15
Members play basketball and volleyball = 26
Members play all games = x
Members play only one game = 2x
There are total number of members = 110
From above data we can write,
110 = 20 + 15 + 26 + x + 2x + 2x + 2x
110 = 61 + 7x
7x = 110 - 61
7x = 49
x = 7members
To find,
Member play basketboll altogether
= 20 + 26 + 2x + x
We know that x = 7,
= 20 + 26 + 14 + 7
= 67 members
Answer:
x = 55
Explanation:
In a parallelogram, the sum of each two consecutive angles is 180°.
In the given parallelogram ABCD, we can note that angles A and B are consecutive angles. This means that their summation is 180°
Therefore:
∠A + ∠B = 180
2x + 15 + x = 180
3x + 15 = 180
3x = 180 - 15
3x = 165
x = 165 / 3
x = 55
Now we can check:
angle A = 2(55) + 15 = 125°
angle B = 55°
angle A + angle B = 125 + 55 = 180°
Hope this helps :)
