does anyone know how to do this. im dumb and need help please i will put 30points if someone actually helps
Oksana_A [137]

Answer:

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

Darren has a wooden board that is Three-fifths of a meter long. He cuts the board into 3 equal parts. How long is each section o
Alik [6]

Answer:

Each section of the board is 1/3 or 0.334(0.333333333333) of a meter

Step-by-step explanation:

3/5 divided by 3 is the equation we have to do.

3/5 divided by 3 is also equal to 3/5 times the reciprocal of 3 or 1/3

3/5 * 1/3

3*1 = 3

5*3 = 15

3/15 which can simplify to 1/3. (divide numerator and denominator by 3.)

Each section of the board is 1/3 or 0.334(0.333333333333) of a meter
