how to make 105° using compass and ruler

Answer 1

To make 105° using compass and pencil...
The easiest steps are :-

1) Frist of all construct a 60° angle
2) Then draw a 90° Angle from that point and bisect it (p.s -> draw that 90° roughly ). The bisector of 90° is 45°

3) Then mesure the 45° and add it up on ur 60°

Here uh get ur 105°

Thanks....mark as brainliest if satisfies!:)

Answer 2

Answer:

Step-by-step explanation:hey actually u will get :

1+2tan21 * cot21 * cot13 * tan13. ( * means multiplication)

3( tan72/ cot(90-72) - 2( sin54/cos(90-54)^3 + 2cot(90-21) cot21 ....(same using complementary angles u will get solution)
