A) 13 degrees because it would be 90-77
If two angles are complementary, then the two angles add up to 90 degrees.
If angle A is 77, then the complement would be 90-77 or 13 degrees.

b) The complement of the complement of the angle is the angle itself.
Say the angle A is 30 degrees. It's complement is 90-30 or 60 degrees.
The complement of the 60 degrees is 30 degrees.
So the complement of the complement of the angle would be the angle itself.

Hope this helps :)

Ne4ueva [31]

Answer:

242 pages.

Step-by-step explanation:

Let x represent number of pages that Claudia read last week.

We have been given that Claudia is reading a book that has 360 pages. She read some of the book last week. She plans to read 46 pages today. When she does,she will be 4/5 of the way through the book.

The number of total page left after reading 46 pages and x pages last week will be equal to 4/5 of 360.

We can represent this information in an equation as:

$x+46=\frac{4}{5}\cdot 360$

Let us solve for x.

$x+46=4\cdot 72$

$x+46=288$

$x+46-46=288-46$

$x=242$

Therefore, Claudia read 242 pages last week.

Pleaseeee help!!!!!! I will mark you as brainlinest for correct answer!!!!!!!!!!!

Agata [3.3K]

I believe the answer you are looking for is the quadratic formula. because it has the formula correct, and it to me just looks exactly like it.

So, it has the ax^2+bx+c=0 but just a little difference, it has a subtracting sign instead of adding.

I don't know if I am right, but that is my guess. I remember doing those lol
