Answer:

  cos(θ) = (√33)/7

Step-by-step explanation:

The relevant relation is ...

  cos(θ) = √(1 -sin²(θ))

  cos(θ) = √(1 -(4/7)²) = √(1 -16/49) = √(33/49)

  cos(θ) = (√33)/7

Answer:

x = 7

Step-by-step explanation:

The angles are alternate interior angles, so for the lines to be parallel, the angle measures must be equal.

7x - 7 = 4x + 14

3x = 21

x = 7

What is the positive solution of x square minus 36 equals 5x
777dan777 [17]
Answer:

<span>⇒x=9</span> (positive solution)

Explanation:

<span><span>x2</span>−36=5x</span>

<span>→<span>x2</span>−36−5x=0</span>

Factor the expression:

We get:

<span><span>(x−9)</span><span>(x+4)</span>=0</span>

First solution:

<span>⇒<span>(x−9)</span>=<span>0<span>x+4</span></span></span>

<span>⇒<span>(x−9)</span>=0</span>

<span>⇒x=<span>9</span></span>

<h3>Answer:   7 goes in the blank space</h3>

The range of values for x is 2 < x < 7

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

Explanation:

The hinge theorem says that the larger the opposite side is, the larger the angle will be.

AD = 11, DC = 8

Since AD > DC, this means angle ABD > angle DBC.

--------

angle ABD > angle DBC

20 > 4x-8

20+8 > 4x-8+8 ... add 8 to both sides

28 > 4x

4x < 28 ... flip both sides and the inequality sign

4x/4 < 28/4 ... divide both sides by 4

x < 7

--------

At the same time, the angle 4x-8 cannot be 0 or negative.

So we say 4x-8 > 0. Let's solve this for x.

4x-8 > 0

4x-8+8 > 0+8 ... add 8 to both sides

4x > 8

4x/4 > 8/4 ... divide both sides by 4

x > 2

2 < x ... flip both sides and the inequality sign

--------

We have 2 < x and x < 7. Both of these combine to the compound inequality 2 < x < 7

We can pick any value between 2 and 7 as long as we dont pick x = 2 or we dont pick x = 7.
