C1 CD​

Answer 1

Answer:

: Draw a pair of tangents to a circle of radius 4\ cm4 cm which are inclined to each other at an angle of 70\ degree70 degree .

To Find: Required Diagram.

Step-by-step explanation:

The tangents can be constructed in the following manner:

Draw a circle of radius 4\ cm4 cm and with center as OO .

Take a point AA on the circumference of the circle and join OAOA . Draw a perpendicular to OAOA at point AA .

Draw a radius OBOB , making an angle of (180-70)=110\ degree(180−70)=110 degree with OAOA .

Draw a perpendicular to OBOB at point BB . Let both the perpendiculars intersect at point PP . PAPA and PBPB are the required tangents at an angle of 70\ degree70 degree .

Now, The required tangents are PA\ and\ PBPA and PB as shown in the figure.

Answer 2

Answer:

70

Step-by-step explanation:

1) Draw a circle of radius 4cm Draw a line on the point of 4 cm

2) 180-70 =100 take protractor keep on the point and measure 110 from protractor.
