Let's use a formula in order to find how much the interior angles are supposed to add up to.

(n-2)×180; n is the number of angles.

(5-2)×180= 3×180=540

We need for the interior angles to add up to 540. Let's make an equation.

100+102+108+121+x=540

431+x=540; let's find x.

540-431= 109

So, X= 109°

What is m∠2?<br> What is m∠1?

Greeley [361]

Answer:

<2 = 75

<1 = 105

Step-by-step explanation:

<2 and 75 are alternate interior angles and since the lines are parallel, they are equal

<2 = 75

<2 + <1 = 180 since the angles form a line

75+ <1 = 180

Subtract 75 from each side

<1 = 180-75

<1 = 105

A recipe for apple pie calls for 1.2 kilograms of apples. If the average apple has a mass of 200 grams, how many apples should b

lutik1710 [3]

Answer:

6Apples

Step-by-step explanation:

Number of apples required for the recipe = 1.2kilograms

But we know that 1000g = 1kg

So;

1.2 kg will give:

1.2 x 1000 = 1200kg

Average mass of the apple = 200g

So;

The number of apples used = $\frac{1200}{200}$ = 6Apples

${a}^{m} \div {a}^{n} = {a}^{m - n}$

<h3>Explanation :</h3>

${a}^{m} \div {a}^{n} = {a}^{m - n}$

${a}^{m} \times {a}^{n} = {a}^{m + n}$

$( {a}^{m}){}^{n} = {a}^{m \times n}$
