Answer:

Part a) The measure of the missing angle is 90\°

Part b) The triangle of the figure is a right triangle

Part c) The triangle of the figure is a scalene triangle

Step-by-step explanation:

we know that

The sum of the interior angles of a triangle is equal to 180\°

so

Let

x------> the missing angle

we know that

x\°+50\°+40\°=180\°

solve for x

x=180\°-90\°=90\°

The triangle of the figure is a right triangle --------> by its angles

Because the triangle has an angle measure of 90\°

The triangle of the figure is a scalene triangle --------> by its sides

Because the three angles and the three sides measures are different

Answer:

The answer is 90.

Step-by-step explanation:

All you have to do is add 50+40 to get 90. Next subtract that from 180 to get 90.

1. Find Angle A :

  • x  + 24 = 3x

  • 3x - x =   2 4

  • 2x = 24

  • x = 12

Angle A :

  • 3x

  • 3 \times 12

  • 36 \degree

2. Find Angle B :

  • 10x - 27 = 7x

  • 10x - 7x = 27

  • 3x = 27

  • x = 9

Angle B :

  • 10x - 27

  • (10 \times 9) - 27

  • 90 - 27

  • 63 \degree

Find Angle C :

  • 5x + 1 = 6x  - 13

  • 6x - 5 x =  1 + 13

  • x = 14

Angle C :

  • 5x + 1

  • (5 \times 14) + 1

  • 70 + 1

  • 71 \degree

Find Angle D :

  • 6x  +  3 = 4x + 39

  • 6x - 4x = 39  -  3

  • 2x = 36

  • x = 18

Angle D :

  • 4x + 39

  • (4 \times 18) + 39

  • 72 + 39

  • 111\degree

And it's given :

  • 36° = Angle A = B

  • 63° = Angle B = A

  • 71° = Angle C = H

  • 111° = Angle D = E

Therefore, the answer will be " BAHE "

Graph ARST with vertices R(6, 6), S(3, -6), and T(0, 3) and its image after a
padilas [110]

Answer:

The answer is the second figure and the vertices of Δ R'S'T' are:

R' = (-6 , 6) , S' = (-3 , -6) , T' = (0 , 3)

Step-by-step explanation:

* Lets revise some transformation

- If point (x , y) reflected across the x-axis

 ∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

 ∴ Its image is (-x , y)

- If point (x , y) reflected across the line y = x

 ∴ Its image is (y , x)

- If point (x , y) reflected across the line y = -x

 ∴ Its image is (-y , -x)

- Now we can solve the problem

∵ R = (6 , 6) , S = (3 , -6) , T = (0 , 3), they are the vertices of ΔRST

- The triangle RST is reflected over the y-axis

- According to the rule above the signs of x-coordinates will change

∵ R = (6 , 6)

∴ Its image is (-6 , 6)

∵ S = (3 , -6)

∴ Its image is (-3 , -6)

∵ T = (0 , 3)

∴ Its image is (0 , 3)

* Now lets look to the figure to find the correct answers

- The image of Δ RST is ΔR'S'T'

∵ The vertices of the image of ΔRST are:

  R' = (-6 , 6) , S' = (-3 , -6) , T' = (0 , 3)

* The answer is the second figure

A group of 5 families at Baileys Middle School sold magazine subscriptions to raise money for the school. ​ $6.00, $7.00, $4.00,
mash [69]

Answer:

The median amount of money raised is $5.00

Step-by-step explanation:

To find the median amount of money raised, we will follow the steps below:

First, arrange the data giving in ascending order. That is

$6.00, $7.00, $4.00, $5.00, $3.00

We will arrange it in ascending order, hence

$3.00, $4.00, $5.00,  $6.00, $7.00

The median is the middle number, we will now proceed to take the middle number.

The middle number is $5.00

Therefore, the median amount of money raised is $5.00
