Answer:

142° is the measure of angle 2.

Step-by-step explanation:

When two lines intersect, they make four angles. The angles facing each other are equal.

Let's say that two lines a and b intersected each other to make angles 1,2,3 and 4 respectively.

The measure of angle 3 = 38 degrees.

We know that the angle 1 is against angle 3 and is equal to 38.

Also Angle 2 and Angle 4 are also against each other and are equal let's say equal to x degrees.

Now, the sum of all four angles = 360 degrees

∠1 + ∠2+ ∠3 + ∠4 = 360°

38° + x + 38° + x = 360°

2x = 360° - 76°

2x = 284°

x = 142°

Hence, ∠2 = 142°

The first five terms of a sequence are 2, 5/3, 3/2, 7/5 and 4/3. what is the explicit formula?
katen-ka-za [31]

Answer:

  an = (n+3)/(n+1)

Step-by-step explanation:

The sequence can be written as ...

  4/2, 5/3, 6/4, 7/5, 8/6, ...

where the first numerator is n+3 and the first denominator is n+1. Each numerator and denominator increase by 1 from term to term, so the explicit formula can be written

  an = (n+3)/(n+1)

Draw Conclusions The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3? Explain
Anon25 [30]

Answer:

The product represent the number 3\times 0.3=0.9

Step-by-step explanation:

To find : The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3?

Solution :

0.3 represents 0.3=\frac{3}{10}

0.9 represents 0.9=\frac{9}{10}

If we multiply 0.3 by 3 we get 0.9

As, 3\times 0.3=3\times \frac{3}{10}

3\times 0.3=\frac{9}{10}

3\times 0.3=0.9

Therefore, The product represent the number 3\times 0.3=0.9
