The three little lines through the sides of the triangle mean all three sides are equal. Because all three sides are equal the three inside angles would aso be equal.


The three angles of a triangle need to equal 180, so we can divide 180 by 3 to find what each angle is:

180 / 3 = 60.


Now we can set the equation with x in it to equal 60:


7x +4 = 60

Subtract 4 from each side:

7x = 56

Divide each side by 7:

x = 56 / 7

x = 8

Lelu [443]

Answer:

See picture.

Step-by-step explanation:

This line is in point slope form y - y_1 = m(x-x_1) where (x_1, y_1) is a point on the line. Begin graphing the line by first graphing the point (-3, 3) from the equation. Then move up 1 unit and over 2 units according to slope. This new point is (-1,4).

X/2 = 8<br> anyone know how to work this out?
Alexus [3.1K]

X/2 = 8

▶ ️2 = 8 × X. (transposing X to RHS )

▶️ 2 = 8X

▶ ️X = 8/2. (transposing 2 to RHS )

▶️ X = 4

hence the value of X is 4.

What is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet?
mafiozo [28]

Answer:

The height of the tank is 0.5 yards.

Step-by-step explanation:

To determine what is the height, in yards, of a cylindrical water tank that holds 1,884 cubic yards of water and has a diameter of 120 feet, knowing that the volume of a cylinder is equal to pi multiplied by the radius squared, multiplied by the height, the following calculation must be done:

1 foot = 0.3333 yards

R = Diameter / 2

R = 120/2 = 60

3.14 x 60 ^ 2 x H = 1,884

3.14 x 3,600 x H = 1,884

3.14 x 1,200 x H = 1,884

3.768 x H = 1.884

H = 1,884 / 3,768

H = 0.5

Therefore, the height of the tank is 0.5 yards.
