Answer:

x =19.2

y=29.8

Step-by-step explanation:

We will use the law of sines to solve this problem

sinA sin B

----------- = -------------

a b

sin 55 sin 40

--------- = ---------------

24.5 x

Using cross products

x sin 55 = 24.5 sin 40

Divide by sin 55

x = 24.5 sin 40 / sin 55

x =19.22512011

To one decimal place

x =19.2

To find the angle opposite y, we know the three angles of a triangle add to 180

y = (180-40-55) = 85

sin 55 sin 85

--------- = ---------------

24.5 y

Using cross products

y sin 55 = 24.5 sin 85

Divide by sin 55

y = 24.5 sin 85 / sin 55

y =29.79516474

To one decimal place

y=29.8

The measure of the supplement of an angle is 60 degrees less than four times the measure of the complement of the angle. Find th

Kisachek [45]

Answer:

Step-by-step explanation:

angle:: x

complemet: 90-x

supplement: 180-x

Equation:

180-x = 4(90-x)+60

180-x = 360 -4x + 60

3x = 240

x = 80 degrees (the angle)

90-x = 10 degrees (the complement)

180-x = 100 degrees (the supplement)

A class survey found that 29 students watched television on Monday, 24 on Tuesday, and 25 on Wednesday. Of those who watched TV

gizmo_the_mogwai [7]

Answer:

There were 49 students in the class

Step-by-step explanation:

To solve this problem, we must build the Venn's Diagram of this set.

I am going to say that:

-The set A represents the students that watched TV on Monday

-The set B represents the student that watched TV on Tuesday.

-The set C represents the students that watched TV on Wednesday.

We have that:

$A = a + (A \cap B) + (A \cap C) + (A \cap B \cap C)$

In which a is the number of students that only watched TV on Monday, $A \cap B$ is the number of adults that watched TV both on Monday and Tuesday, $A \cap C$ is the number of students that watched TV both on Monday and Wednesday, and $A \cap B \cap C$ is the number of students that watched TV on every day.
