Answer:
Angle L*; 67.5 degrees
Angle S*; 22.5 degrees
Step-by-step explanation:
Angle L is 3 times bigger than Angle S.
With this information, we can make an equation.
L=3S
Complementary angles add up to 90 degrees.
90 = 3S + S
90 = 4S
22.5
Angle S equals 22.5.
Because Angle L is 3 times bigger than Angle S, we multiply 22.5 by 3.
This gives us 67.5.
Angle L is 67.5 degrees
Angle S is 22.5 degrees
Now, in order to check our work, we add the two angles together.
67.5 + 22.5 = 90
Because they add up to 90 degrees, the complementary angles work with each other meaning that we are correct
*Angle L is the larger angle
**Angle S is the smaller angle
He needs to have 5 rows of 5 seats if there will be 25 people because 5 x 5 = 25

Because which numbers will make the expessions undefined. We will focus on the denominator only.
Factor the terms.

Now which 2 numbers that will make these terms become 0?
12 and - 1 of course.
So these 2 numbers that will make the expressions undefined are 12 and - 1
Y/3 + 1/4 = 5/12
4y/12 + 3/12 = 5/12
4y/12 = 2/12
4y = 2
/4 /4
y = 1/2
Therefore y = 1/2
It is very simple it would be positive but would remain 35
