The measures of two complementary angles are 6y+3 and 4y−13 . Find the measures of the angles.

Cerrena [4.2K]

Y = 10 degrees

work:
6y + 3 + 4y - 13 = 90
6y + 4y = 90 + 13 - 3
10y = 100
y = 10

Answer:

Distance between the school and the theater = $2\sqrt{13}$ units

Step-by-step explanation:

Use distance formula to calculate the distance from the school (8, 7) and the theater (2, 3):

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$school (8, 7) = (x_1, y_1)$

$theater (2, 3) = (x_2, y_2)$

Plug in the values into the distance formula

$d = \sqrt{(2 - 8)^2 + (3 - 7)^2}$

$d = \sqrt{(-6)^2 + (-4)^2}$

$d = \sqrt{36 + 16} = \sqrt{52}$

Simplify

$d = \sqrt{4 \times 13}$

$d = 2\sqrt{13}$

3. What three numbers are the Pythagorean triple generated by using 4 for x and 1 for y. Remember to use the formulas:

Doss [256]

Given:

Consider the three number are given by:

$a=x^2-y^2$

$b=2xy$

$c=x^2+y^2$

To find:

The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.

Solution:

We have,

$a=x^2-y^2$

$b=2xy$

$c=x^2+y^2$

Substituting 4 for x and 1 for y, we get

$a=4^2-1^2$

$a=16-1$

$a=15$

Similarly,

$b=2(4)(1)$

$b=8$

And,

$c=4^2+1^2$

$c=16+1$

$c=17$

The three three numbers are the Pythagorean triple are 8,15 and 17.

Therefore, the correct option is C.
