Question

plz help in q.16 and if you can solve 17 then that also plz....

Answer 1

Question 16:

As we know that the total angle produced around a point is 360°.

(i) 60° + 40 + 100 +45 +75 +x =360°

x = 360° - 320°

x = 40°

(ii)30 + 75 + 40 +45 +85 +x =360°

x = 360° - 275°

x = 85°

Question 17:

(i) Angle AOD & Angle COB

angle AOC & angle DOB

(ii) angle EOC & angle DOF

angle AOE & angle FOB

angle AOD & angle COB

(iii) angle AOC & angle DOF

ANGLE AOB & ANGLE FOE

ANGLE COB & ANGLE DOE

ANGLE AOD & ANGLE COF

Use the sign of angle instead of writing angle. And put the sign of degree after all the numbers in question 16.
