Find the lengths the missing side
aalyn [17]

Answer:

  • Long leg = 10√3
  • Short leg = 10
  • Hypotenuse = 20

Step-by-step explanation:

<u>Concept: </u>

Here, we need to know the idea of a special triangle 30-60-90.

A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist.

The ratio between the corresponding side of each angle is 1 : √3 : 2

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

30-60-90 ⇔ 1 : √3 : 2

Given the side corresponding to 90° is 20

30° : 90° = 1 : 2

30° : 20 = 1 : 2

30° = 10

30° : 60° = 1 : √3

10 : 60° = 1 : √3

60° = 10√3

Hope this helps!! :)

A baseball team had 70 players show up for tryouts last year and this year had 85 players show up for tryouts. Find the percent
Mashutka [201]

Answer:percent increase in players from last year to this year= 7.14%

Step-by-step explanation:

percent increase = (Increase  in number of players /Initial value of players Last year)  x 100

value of players for tryouts  last year = 70

value of players for tryouts this year = 85

Increase in tryouts = 85-70 =5

percent increase = 5/70 x 100

= 7.14%

Find the values for x and y
Kruka [31]

Look at the picture.

x=90

\angle B\cong\anlge C\to m\angle B=m\angle C=47^o

We know, the sum of the measures of the triangle is equal 180°.

Therefore in ΔBCD we have:

y+47+90=180

y+137=180             <em>subtract 137 from both sides</em>

y=43

Answer: x° = 90°, y° = 43°.

A function is great to represent the cost per person to attend the school dance. What restrictions would be made to the domain
Cloud [144]

Answer:

(0, ∞)

Step-by-step explanation:

Take a look at "cost per person."  This involves dividing the total paid for admission tickets divided by the number of people attending.  Obviously this function would not be defined for zero attendees or for partial attendees.  Thus, the domain is made up of all integers greater than zero.
