Answer:

x ≈ 61.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = \frac{adjacent}{hypotenuse} = \frac{20}{x} ( multiply both sides by x )

x × cos71° = 20 ( divide both sides by cos71° )

x = \frac{20}{cos71} ≈ 61.4 ( to the nearest tenth )

<h3>Answer:  61.4</h3>

====================================================

Explanation:

Use the cosine ratio to get the following,

cos(angle) = adjacent/hypotenuse

cos(71) = 20/x

x*cos(71) = 20

x = 20/cos(71)

x = 61.431 approximately

x = 61.4

Notes:

  • The hypotenuse is always the longest side of any right triangle, so x must be larger than 20.
  • Make sure your calculator is in degree mode.

The first sentence in the chart belongs to the subjunctive mood, while the other sentences can be classified as part of the conditional mood.

<h3>What is a verb mood?</h3>

In language, the verb mood indicates the attitude of the speaker, and therefore, it provides clues about the way language is used. For example, the imperative mode indicates an order is being given.

<h3>What is the difference between the conditional and the subjunctive mood?</h3>
  • Subjunctive: It is used for expressing wishes; due to this, it is common to find the use of words such as "wish".
  • Conditional: It expresses a condition or a situation that will/can happen if another situation occurs. This can be identified due to the use of "if".

Based on this, the first sentences belongs to the subjunctive mood, while the other sentences are part of the conditional.

Find the first 4 terms of the geometric sequence a1=40 and r=0.5
DedPeter [7]
For the answer to the question above, 
a1 = 40 
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>

<span>a5 = (1/2^4) 40 = 40/16 = 2.5
</span>
So the answer to your question is 2.5
I hope my answer helped you. Feel free to ask more questions. Have a nice day!

BRIANILEST!!!!Which lines are parallel? Check all that apply.
spin [16.1K]

Answer:

b║f

c║e

Step-by-step explanation:

Given a diagram,

Lines b, c, d, e, f and a transversal line 'a'.

Here line 'b' makes an angle with line 'a' is 89.5° and line 'f' makes an angle with line 'a' is also 89.5° (180°-90.5° = 89.5°)

Since corresponding angles are same.

So, line 'b' is parallel to line 'f'.

And line 'c' makes an angle with line 'a' is 91.5° and line 'e' makes an angle with line 'a' is also 91.5° (180°-88.5° = 91.5°)

Since corresponding angles are same.

So, line 'c' is parallel to line 'e'.

Therefore,

b║f

c║e

That's the final answer.
