<h2><em><u>Answer</u></em><em><u>:</u></em><em><u>-</u></em></h2>

\pink{\bigstar} The measure if ∠x \large\leadsto\boxed{\tt\purple{43^{\circ}}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• <u>To</u><u> </u><u>Find</u><u>:</u><u>-</u>

  • Measure of \angle x

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• <u>Solution</u><u>:</u><u>-</u></h3>

The given angles are made by a straight line. We know that the total angle made by a straight line is 180°.

Therefore, all the angles should sum upto 180°.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

•<u> Working:-</u>

➪ \sf (x + 31^{\circ}) + (x + 20^{\circ}) + (x) = 180^{\circ}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x + 31^{\circ} + x + 20^{\circ} + x = 180^{\circ}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf 3x + 51^{\circ} = 180^{\circ}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf 3x = 180^{\circ} - 51^{\circ}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf 3x = 129^{\circ}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ \sf x = \dfrac{129}{3}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ \large{\bold\red{x = 43^{\circ}}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the measure of the ∠x is 43°.

Tell whether the argument below is an example of inductive or deductive reasoning.
Lilit [14]

Answer:

Deductive Reasoning

Step-by-step explanation:

We take the statement as true,

"...all dogs in the kennel are collies..."

we also take

- collies are a type of dog

and

- Rover is a dog

So if Rover is a dog, and all dogs in the kennel are collies, then Rover is a collie, because he is a dog and inside the kennel (after we take the statement all dogs in the kennel are collies).

This type of reasoning follows the Deductive Reasoning pattern, if A = B, and B is C then A is also C.

While inductive takes that if A = B, and C is B just like D is B, then E is also B.

Joe has a bag of blocks. 3 red blocks and 2 blue blocks weigh 24 ounces while 1 red block and 3 blue blocks weigh 16 ounces. Def
fredd [130]

Answer: 3r + 2b = 24

r + 3b = 16

Step-by-step explanation:

Let the red blocks be represented by r

Let blue blocks be represented by b

Since 3 red blocks and 2 blue blocks weigh 24 ounces. This will be:

3r + 2b = 24

1 red block and 3 blue blocks weigh 16 ounces. This will be:

r + 3b = 16

Therefore, the equation will be:

3r + 2b = 24

r + 3b = 16
