The angle measures are represented by algebraic expressions.
Anuta_ua [19.1K]

Answer:

The value of x is 0.5

The value of y is 0.8

The value of z is 0.9

Step-by-step explanation:

* Lets explain how to find the values of x , y and z

- <u><em>From the attached figure</em></u>

# l_{1} and l_{2} intersect each other at a point

- When two lines intersect each other at a point they formed

 congruent vertical opposite angles

∴ The angle of measure (50z + 13)° = the angle of measure (80z - 14)°

  because thy are vertical opposite angles

∴ 50z + 13 = 80z - 14

- Add 14 to both sides

∴ 50z + 27 = 80z

- Subtract 50z from both sides

∴ 27 = 30z

- Divide both sides by 30

∴ z=\frac{27}{30}=\frac{9}{10}=0.9

* The value of z is 0.9

- <u><em>From the attached figure</em></u>

# The angles of measures (50z + 13)° and (45x + 19/2)° have sum

   of 90°

∴ 50z + 13 + 45x + 19/2 = 90

∵ z = 0.9

∴ 50(0.9) + 13 + 45x + 19/2 = 90

∴ 45 + 13 + 45x + 9.5 = 90

- Add like term in the left hand side

∴ 67.5 + 45x = 90

- Subtract 67.5 from both sides

∴ 45x = 22.5

- Divide both sides by 45

∴ x = 0.5

* The value of x is 0.5

- <u><em>From the attached figure</em></u>

# There is a ray perpendicular to line l_{1}

∴ The measure of the angle whose measure (225y/2)° is 90°

∴ \frac{225y}{2}=90

- Multiply both sides by 2

∴ 225y = 180

- Divide both sides by 225

∴ y=\frac{180}{225}=\frac{4}{5}=0.8

* The value of y is 0.8

VikaD [51]

Answer:

  500

Step-by-step explanation:

The problem statement tells you ...

  300 = 0.60×voters

Dividing by the coefficient of the variable gives ...

  300/0.60 = voters = 500

500 students voted in the election.
