Slope = (1+3)/(1+2)
slope = 4/3

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 :)
Y is less than x look at the number line
Answer:
172 cm².
Step-by-step explanation:
Total surface area = 56 + 16 +56 + 16 + 14 + 14
Out of all the numbers from 1 to 80, there are (80-20)/(80) = 60/80 = 0.75
of them that are greater than 20 .
So every time you pick one at random, there a 75% chance that it will be
greater than 20.
If everything works out according to pefectly random probabilities, then
in 180 selections, 75% of them = (0.75 x 180) = <em>135 of the selections</em>
would be numbers greater than 20 .
