Find the measure of each numbered angle.

Answers

Answer 1

Answer:

Answer:

∠3 = 22°

∠4 = 22°

∠5 = 88°

Step-by-step explanation:

86 + 72 = 158

180 - 158 = 22

∠3 ≅∠4 they're verticle angles

22+ 70 = 92

180 - 92 = 88

10 ) Which Property of Multiplication is shown? (5 + 3) x 2 = 5 x 2 + 3 x 2A. Identity Property
C. Associative Property
B. Distributive Property
D. Commutative Property

Answers

Property of Multiplication that is shown on the expression (5 + 3) x 2 = 5 x 2 + 3 x 2 is Distributive Property (option b)

The property of multiplication that is shown in the given equation is the Distributive Property. The Distributive Property states that multiplication distributes over addition. In other words, when we multiply a number by the sum of two other numbers, it is the same as multiplying the number by each of the individual addends and then adding the results together.

In the given equation, we have "(5 + 3) x 2 = 5 x 2 + 3 x 2." Let's break down the left-hand side first. "(5 + 3)" represents the sum of 5 and 3, which is 8. So, we have "8 x 2." By applying the Distributive Property, we can rewrite this as "5 x 2 + 3 x 2."

Now, on the right-hand side, we have "5 x 2 + 3 x 2." Here, we are multiplying 5 by 2 and 3 by 2 individually and then adding the products together. This aligns with the Distributive Property, which states that the result will be the same as on the left-hand side.

So, the Main Answer is option B. Distributive Property

Answer:

B. Distributive Property of Multiplication

Step-by-step explanation:

The given equation shows that two similar expressions are equal to each other.

How? Well, they both equal 16 to start. These are the same expressions - one is just distributed out!

$2 \cdot (5 + 3) \n2 \cdot 5 + 2 \cdot3 \n10 + 6 = 16$

and...

$5 \cdot 2 + 3 \cdot 2\n10 + 6\n16$

In the equations, the only difference is that we distributive 2 and multiplied in by 5 and 3!

Which product is positive?

Answers

Option D:

$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$ is positive product.

Solution:

Some basic rules of product:

If the negative sign is in even number of times then the product is positive.

If the negative sign is in odd number of times then the product is negative.

To find which product is positive:

Option A:

$$\left((2)/(5)\right)\left(-(8)/(9)\right)\left(-(1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative signs = 3 which is odd

So, the product is negative.

Option B:

$$\left(-(2)/(5)\right)\left((8)/(9)\right)\left(-(1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative signs = 3 which is odd

So, the product is negative.

Option C:

$$\left((2)/(5)\right)\left((8)/(9)\right)\left((1)/(3)\right)\left(-(2)/(7)\right)$

Here, number of negative sign = 1 which is odd

So, the product is negative.

Option D:

$$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$

Here, number of negative sign = 2 which is even

So, the product is positive.

Hence option D is the correct answer.

$\left(-(2)/(5)\right)\left(-(8)/(9)\right)\left((1)/(3)\right)\left((2)/(7)\right)$ is positive product.
