Show that the angles A and B are congruent

Answer:

$\angle A =\angle B =90^\circ$

Step-by-step explanation:

The diagram of the sled kite is attached below.

The central part of the kite is square.

We know by the property of a square that all its angles are congruent and equal to 90 degrees.

Therefore:

$\angle A =\angle B =90^\circ$

Angles A and B are congruent.

Answer:

470 cm³

Step-by-step explanation:

Volume of rectangular prism = width × length × height

⇒ Volume of whole rectangular prism = 9 cm × 10 cm × 8 cm

= 720 cm³

Side lengths of the missing piece:

width = 5 cm
length = 10 cm
height = 8 cm - 3 cm = 5 cm

⇒ Volume of the missing piece = 5 cm × 10 cm × 5 cm

= 250 cm³

⇒ Volume of irregular figure = 720 cm³ - 250 cm³

= 470 cm³

Enter the correct value so that each expression is a perfect square trinomial

myrzilka [38]

Answer:

Step-by-step explanation:

1). x² - 10x + a²

By using the formula of (a - b)² = a² - 2ab + b²

x² - 2(5)x + a²

Therefore, for a perfect square of the expression a should be equal to 5.

Therefore, (x² - 10x + 25) will be the answer.

2). x² + 2ax + 36

= x² + 2(a)x + 6²

For a perfect square of the given expression value of a should be 6.

x² + 2(a)x + 6² = x² + 2(6)x + 6²

= (x + 6)²

Therefore, x² + 12x + 36 will be the answer.

3). $x^{2}+\frac{1}{2}x+a^2$

$x^{2}+2(\frac{1}{4})x+a^2$

To make this expression a perfect square,

a² = $(\frac{1}{4})^2$

$x^{2}+2(\frac{1}{4})x+(\frac{1}{4})^2$ = $(x+\frac{1}{4})^2$

Therefore, the missing number will be $\frac{1}{16}$ .
