Answer:

-214.

Step-by-step explanation:

3x - 22y When x = 2 and y = 10 we have:

3(2) - 22(10)

= 6 - 220

= -214.

Triangle A has side lengths of 10 units, 24, units, and 26 units. Ryan cut out 2 copies of triangle A and joined them together t

sergejj [24]

Answer:

Perimeter of Rectangle will be 68 units.

Step-by-step explanation:

Given:

Length of side 1 = 10 units

Length of side 2 = 24 units

Length of side 3 = 26 units

Now we will check whether the triangle A is right angle triangle or not;

$(Length of side 3)^{2} = 26^2 = 676$

$(Length of side 2)^{2} = 24^2 = 576$

$(Length of side 1)^{2} = 10^2 = 100$

Now From above we can see that;

676 = 576 + 100

Hence we can say ;

$(Length of side 3)^{2} = ](Length of side 2)^{2} + (Length of side 1)^{2}$

By Converse of Pythagoras theorem.

"Hence When the square of the length of the hypotenuse is equal to sum of the square of other two sides we can say that triangle is a right angled triangle."

Now Given:

Ryan cut out 2 copies of triangle A and joined them together to form a rectangle.

So we can say that the hypotenuse side of the triangle will become diagonal of the rectangle and other two side will become length and width.

Now;

Length of rectangle = 24 units

Width of rectangle = 10 units.

We need to find the perimeter of rectangle.

Now Perimeter of rectangle is 2 times sum of Length and width.

framing in equation form we get;

Perimeter of rectangle = $2(l+w) = 2\times (24+10) = 2\times 34 =68 units.$

Hence Perimeter of Rectangle will 68 units.

a pole that is 3.3 M tall casts a shadow that is 1.22 M long at the same time a nearby Tower cast a shadow that is 50.75 M long

jenyasd209 [6]

Since there is no distance between the pole and the base of the tower, we can assume that the pole is at the base of the tower.
We can create a right triangles between the pole and its shadow and between the tower and its shadow as shown in the figure. Let $x$ be the height of the tower. Since our triangles are similar the ratio between its sides is going to be proportional, so we can establish a proportion to find $x$ :
$\frac{x}{3.3} = \frac{50.75}{1.22}$
$x= \frac{(50.75)(3.3)}{1.22}$
$x=137.27$

We can conclude that the tower is 137.27 meters tall.
