Answer:

<h2><u><em>24</em></u></h2>

Step-by-step explanation:

The Pythagoras theorem formula states that in a right triangle ABC, the square of the hypotenuse is equal to the sum of the square of the other two legs. If AB, BC, and AC are the sides of the triangle, then: BC2 = AB2 + AC2​. While if a, b, and c are the sides of the triangle, then ​c2 = a2 + b2.

Tell whether the angles are adjacent or vertical. Then find the value of x.
lozanna [386]

Answer:

x = 25

Step-by-step explanation:

The angles are vertical since they form from two lines crossing at a point and they share a same vertex.

Vertical angles are equal so

4x - 25 = 75

4x = 100

x = 25

Solve by substitution<br> 3x-4y=-4<br> y=2x-4
dybincka [34]

Answer:

x=4 and y=4

Step-by-step explanation:

From first function we have:

3x - 4y =  - 4 \\ 4y = 3x  + 4

And from the second one:

y = 2x - 4 \\ 4y = 8x - 16

Substitute them:

4y = 3x + 4 \\ 4y = 8x - 16 \\  \\ 0 =  - 5x + 20 \\ x = 4 \\ y = 4
