Answer:
x =8
The angles are
3x= 24
7x+4 = 60
13x-8 =96
Step-by-step explanation:
The sum of the angles of the triangle is 180
3x+ 7x+4 + 13x-8 =180
Combine like terms
23x -4 = 180
Add 4 to each side
23x -4+4 =180+4
23x =184
Divide by 23
23x/23 = 184/23
x =8
The angles are
3x= 3*8 =24
7x+4 = 7*8+4 = 56+4 = 60
13x-8 = 13*8-8 =104-8=96
Answer:
39 ft
Step-by-step explanation:
Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.
Pythagorean theorem:
.... which a and b are the two sides while x is the diagonal.


... now we square root both sides

Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.
13 * 3 = 39 ft
12 m is the area! hope i could help
Answer:3,600
Step-by-step explanation:
Find the Prime factorization of 400: 2x2x2x2x5x5
Find the Prime factorization of 900: 2x2x3x3x5x5
Multiply each factor the greater number of times it occurs: 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5= 3,600
