Answer:

x = 14

Step-by-step explanation:

When angles are complementary, it means that they add up to 90°.

This means that (4x)°+(2x+6)° = 90°, or (4x)+(2x+6) = 90  (Got rid of degree signs).

Now solve for x.

(4x)+(2x+6) = 90

simplify

4x+2x+6 = 90

-6 both sides

4x+2x = 84

simplify

6x = 84

÷6 both sides

x = 14

Answer:

14

Step-by-step explanation:

the sum of the terms in the angle is 6x+6. Since the angles ate complementary their sum is 90 so you set the aforementioned sum equal to 90. You then solve for x and get 14.

Find the diagonal of a square whose sides are of the given measure. Given = 6sqrt2
jeyben [28]

Answer:

=12 units

Step-by-step explanation:

When a square is cut along one diagonal, it forms a right angled triangle whose legs are the sides of the square and the hypotenuse is the diagonal of the square.

Therefore, the Pythagoras theorem is used to find the hypotenuse.

a² + b² = c²

(6√2)²+(6√2)²=c²

72+72=c²

c²=144

c=√144

=12

The diagonals of the square measure 12 units each.

andriy [413]

Answer:

The students can group themselves in 360360 ways

Step-by-step explanation:

For this exercise we need to use the following equation:

\frac{n!}{n1!*n2!*...*nk!}

This equation give us the number of assignation of n elements in k cell, where n1, n2, ..nk are the element that are in every cell

In this case we have 15 student that need to be assign in three vehicles with an specific capacity. This vehicles would be the equivalent to cells, so we can write the equation as:

  \frac{15!}{7!*5!*3!}

Because the first vehicle have 7 seating, the second vehicle have 5 seating and the third vehicle have 3 seating.

Solving the equation we get 360360 ways to organized 15 students in three vehicles with capacity of 7, 5  and 3 seating.
