Does anyone know how to do this. im dumb and need i will put 30points if someone actually

1 =98

2 = 49

3 = 63

Step-by-step explanation:

Assuming 1 is at the center since it has the dot

<1 = arc 98

<1 = 98

We can find angle 2

<2 = 1/2 the intercepted arc

<2 = 1/2 (98)

<2 = 49

We can find angle 3

Angle formed by 2 chords

<3 = 1/2(arc 70 + arc56)

<3 = 1/2(70+56)

<3 =1/2 (126)

<3 = 63

step-by-step explanation:

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
