Question

A is greater than b by one third of a right angle find te values of a an

Answer 1

Hi thank you for asking the question

A + b =180° [Linear pair]... (1)

 Also, given that

A – b = 1 3 × 90°

⇒a – b = 30°... (2)

On adding equations (1) and (2), we get 2a=210°

⇒a =105°

And

B = 180°−105°

⇒b=75°

∴a = 105° and b = 75°

Hope this answer helps you
