The measure of the central angle AOB is by 30° greater than the measure of the inscribed angle which intercepts arc AB. What are the measures of these angles?
1 answer:
Answer:
inscribed angle: 30° central angle: 60° Step-by-step explanation:
The central angle is double the inscribed angle for the same intercepted arc. Since doubling the angle adds 30° to it, the original inscribed angle must be 30° .
Then the central angle is 30°+30° = 2·30° = 60° .

Answer: 30 boys
Step-by-step explanation:
Boys:Girls
3 : 1
Let no. of girls =x
⇒ no. of boys =3x.
⇒ no. of students in class =4x
=
4/3×3x
= 4
/3 ×no. of boys
40=4/3* no.of boys
40* (3/4)=no.of boys
30=no of boys
