Question

construct a pair of tangents to a circle of radius 3 cm such that angle between the tangent is 40 degree​

Answer 1

Angle b1w radii=180-40

=140

Take compass with 3cm radius n draw a circle

Draw one radius n keep protractor n mark 140 degrees

Take compass from point A cut an arc as shown (with more than half of the line)

Keep compass on the cut arc n cut an arc again. Keep the compass on the arc first arc n draw n arc outside the circle n keep the compass on 2nd arc n cut another arc

Do the same from point B

Join the points A n B

Hope this helps u
