(9x + 20°) + 7x = 180° { supplementary angles}

or, 9x + 20° + 7x = 180 °

or, 16x = 180° - 20°

or, x = 160°/16

:. x= 10°

Now,

9x + 20° + 2y= 180° { supplementary angles}

or, 9* 10 + 20 + 2y= 180°

or, 110° + 2y= 180°

or, 2y= 180° - 110°

or, y= 70°/2

:. y= 35°

ps: double check everything, I don't have a calculator.

Ann reads 10 pages of her book every
Semenov [28]

Answer: Ann read 34 pages that day

Step-by-step explanation:

Ann reads 10 pages of her book everyday

And with every free minute she has she can read 2 pages

With 12 free minutes that day we do the following:

Multiply 12 by 2 to get the number of pages she reads in that free time which equals 24.

Then we add that 24 to the 10 pages she will read regardless.

Which leaves us with 34 pages.

Hope This Helps! :)
