An angle is two rays with a common endpoint, called the vertex. The rays are the sides of the angle.
In the angle ∠XYZ, the vertex is Y, and the sides are rays
and
You can name angles by three letters, X on one side, the vertex Y, and Z on the other side: ∠XYZ and ∠ZYX are both names for this angle. Or an angle can be named by just its vertex, for example, ∠Y, as long as it is the only angle with that vertex.
Therefore, the correct option is B
Answer:11
Step-by-step explanation:
Boys : girls=7:1
Sum of ratio=7+1=8
Let number of girls be y
Then number of boys=y+66
Total number of pupils=y+y+66
Total number of pupils=2y+66
girls only=(girl ratio)/(sum of ratio) x (total number of pupils)
y=1/8 x (2y+66)
Cross multiply
y x 8=2y + 66
8y=2y + 66
Collect like terms
8y-2y=66
6y=66
Divide both sides by 6
6y/6=66/6
y=11
There are 11 girls
