Using linear pairs,

By the exterior angle theorem,

Answer:
35 mins lost
out of 3 and 1/2 hrs = 3.5 x 60 mins = 210 mins
%time lost = time lost/total time x 100
= 35/210 x 100
= 1/6 x 100
= 16.66666 %
3. Simplify to the exponential form
(-2x^5)^4
(-2)^4 • (d^5)^4
16dx^20 is the answer
This is the answer for the question
