Answer:

x=76

Step-by-step explanation:

46+x+20=2x-10

x+66=2x-10

-2x -2x

-x+66= -10

-66 -66

-x= -76

/-1 /-1

x=76 before i finish the rest is that a 46 in the bottom left corner of the triangle in the 1st question

76 might not be right if the angle measure isn't 46

How many different triangles can you make that have angels 60˚, 60˚, 60˚ ?

svet-max [94.6K]

Answer:

Infinite

Step-by-step explanation:

A triangle that has all 60-degree angles is equilateral, which means that all side lengths are the same. However, there are infinite possibilities for the side lengths!

I hope this helped, please give brainliest if this is correct! Thank you!

An online media service offers video and music downloads. Each download of a song costs $1.50. Each download of a video costs 2

svetoff [14.1K]

Answer:10

Step-by-step explanation:

if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15

The exterior walls and roof of a barn are to be painted. The barn is in the shape of a rectangular prism, with an isosceles tria

vlada-n [284]

Given:

The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.

The triangular prism has a base length of 25 feet, a height of 8 feet, and a prism height of 55 feet.

To find:

The total area to be painted.

Solution:

There are 4 external surfaces for the rectangular prism and 4 external surfaces for the triangular prism.

The rectangular prism has 4 rectangles out which there are 2 sets of similar rectangles.

There are two rectangles with lengths of 25 feet and widths of 10 feet while the other two rectangles have lengths of 55 feet and widths of 10 feet.

The area of a rectangle with a length of 25 feet and a width of 10 feet $= 25(10)= 250$ square ft.

The area of two such rectangles $= 2(250) = 500$ square feet.

The area of a rectangle with a length of 55 feet and a width of 10 feet $= 55(10)= 550$ square feet.

The area of two such rectangles $= 2(550) = 1100$ square feet.

The triangular prism has 2 triangles and 2 rectangles.

The triangles have base lengths of 25 feet and heights of 8 feet while the rectangles have lengths of 55 feet and heights of 14.8 feet.

The area of a triangle with a base length of 25 feet and a height of 8 feet $= \frac{1}{2}(25)(8)= 100$ square feet.

The area of two such triangles $=2(100)= 200$ square feet.

The area of a rectangle with a length of 55 feet and a width of 14.8 feet $= 55(14.8)= 814$ square feet.

The area of two such rectangles $= 2(814) = 1628$ square feet.

The total area to be painted $=500+1100+200+1628 = 3128$ square feet.

So an area of 3128 square feet is to be painted.
