I can't see all the triangles, but basically, it is asking you to write down triangles that are congruent with each other.

The marks in the corner of the triangle indicate that the angles of that triangle are congruent to the other triangle.

So,

Triangle NOP= Triangle NQP

Make sure that the points align with each other, otherwise you could be saying that two different triangles are congruent to each other.

N= N O=Q P=P

I hope this cleared some confusion!

Answer:

<h2>10</h2>

Step-by-step explanation:

Given the expression $\sqrt{10} * \sqrt{10}$ . To find the product of this two values, the following steps must be followed.

According to one of the law of indices, $\sqrt{a} = a^{\frac{1}{2} }$

$\sqrt{10} * \sqrt{10}\\= 10^{\frac{1}{2} }* 10^{\frac{1}{2} }\\= 10^{\frac{1}{2}+\frac{1}{2}}\\ = 10^{1} \\= 10$

The product is 10

A ladder is placed against a wall such that the top is 8 feet above the ground. If the ladder is 10 feet long, how far away from

Annette [7]

Answer:

6 feet

Step-by-step explanation:

Consider the right triangle formed by the wall, ladder and ground.

Let the distance the ladder is from the wall be d , then

Using Pythagoras' identity in the right triangle

The square on the hypotenuse ( ladder) is equal to the sum of the squares on the other 2 sides ( wall and d ), then

d² + 8² = 10²

d² + 64 = 100 ( subtract 64 from both sides )

d² = 36 ( take the square root of both sides )

d = $\sqrt{36}$ = 6

That is the ladder is 6 feet away from the wall

Need help on this one

malfutka [58]

Answer:

3

Step-by-step explanation:

To simplify this expression, we will simply work with the numerator, then the denominator, and then the fraction as a whole, following PEMDAS.

Numerator: 12 - 6 + 5 * (-3)^2

= 12 - 6 + 5 * (9)

= 12 - 6 + 45

= 6 + 45

= 51

Denominator: 17

So our simplified fraction is as follows:

51/17

Which can be reduced to the whole number, 3.

Cheers.
