Question

drow a pair of tangent to a circle of radius 4cm which are inclined to each other at an angle of 70% and write the measure of its length

Answer 1

Answer:

To Find: required digram

Step-by-step explanation:

the tangents can be constructed in the following manner

• Draw circle radius 4 cm and with centre as 0
• Take point a as the circumference pf the circle and join O A Draw a perpendicular O A at point A
• Draw a radius O B making a circle angle of (180-70)=110° with O A
• Draw perpendicular to OB at point B. Let both perpendiculars intersect at point B Let intersect at Point P .P A and P B are required tangents at angle 70°

Now the required tangents are PA and PB
