To solve this problem you must apply the proccedure shown below:

 1. You need to apply the formula for calculate the area of a rectangle and the formula for calculate the area of a semicircle, which are:

 - Area of the rectangle:

 A1=bh

 Where b is the base and h is the height

 A1=(4 ft)(2ft)
 A1=8 ft²

 - Area of the semicircle:

 A2=πr²/2

 Where r is the radius.

 A2=π(1 ft)²/2
 A2=1.57 ft²

 2. Therefore, the area of the figure is:

 At=A1+A2
 At=9.57 ft²

 The answer is the:

 A. About 9.57

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.

Please help me i really need help please
vazorg [7]

Answer:

10°

Step-by-step explanation:

x + 25 = 3x + 5. [Vertically Opposite Angles]

=> 25 - 5 = 3x - x

=> 20 = 2x

=  >  \frac{20}{2}  = x

=> 10 = x

=> <u>x = 10</u><u>°</u><u>(</u><u>Ans)</u>
