It should be 10. Since it’s a right angle split in two we know that the total degrees is 90.

60+3x=90
subtract 60

3x=30
divide by 3

x=10

One side of a right triangle has a length of 24 centimeters. What could be the lengths of the other two sides of the right trian

Zanzabum

Answer:

A. 7 centimetres and 25 centimetres

Step-by-step explanation:

To see if the lengths make a triangle, use the Pythagorean theorem. Insert the biggest value as c (the hypotenuse, which is always the longest side in a right triangle). If both sides equal each other, it is a right triangle:

$a^2+b^2=c^2$

$24^2+7^2=25^2\\\\576+49=625\\\\625=625$

This is a right triangle.

$23^2+8^2=24^2\\\\529+64=576\\\\593\neq 576$

Not a right triangle.

$9^2+22^2=24^2\\\\81+484=576\\\\565\neq 576$

Not a right triangle.

$24^2+10^2=27^2\\\\576+100=729\\\\676\neq 729$

Not a right triangle.

Y=2x + 4 y= -10/3 x + 76/3 what is the sum of the x- and y-values in the solution to the system of equations?

Andreyy89

Given:

The system of equations:

$y=2x+4$

$y=-\dfrac{10}{3}x+\dfrac{76}{3}$

To find:

The sum of the x- and y-values in the solution to the system of equations.

Solution:

We have,

$y=2x+4$ ...(i)

$y=-\dfrac{10}{3}x+\dfrac{76}{3}$ ...(ii)

From (i) and (ii), we get

$2x+4=-\dfrac{10}{3}x+\dfrac{76}{3}$

$2x+\dfrac{10}{3}x=\dfrac{76}{3}-4$

$\dfrac{6x+10x}{3}=\dfrac{76-12}{3}$

Multiply both sides by 3.

$16x=64$

Divide both sides by 16.

$x=\dfrac{64}{16}$

$x=4$

Putting x=4 in (i), we get

$y=2(4)+4$

$y=8+4$

$y=12$

The solution of system of equations is (4,12).

$x+y=4+12$

$x+y=16$

Therefore, the sum of the x- and y-values in the solution to the system of equations is 16.
