What is 7x-11-4x=6 equasion
RoseWind [281]

Question:

7x - 11 - 4x = 6

1. Simplify,

3x - 11 = 6

2. Add 11 to both sides

3x - 11 + 11 = 6 + 11

3x = 17

3. Divide 3 from both sides

3x/3 = 17/3

x = 17/3 <===== <em>Answer</em>


Hope this helped!!!

Find the value of each variable<br> x = <br> y=
Karolina [17]

Answer:

x=9

y=9\sqrt{2}

Step-by-step explanation:

This is a special type of triangle known as a 45-45-90 triangle.

The ratio for the sides of this triangle are x:x:x\sqrt{2}

Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.

The hypotenuse, however, is the value of one side multiplied by \sqrt{2}.

In this case it is 9, so 9*\sqrt{2} = 9\sqrt{2}

A safety regulation states that the maximum angle of elevation for a rescue ladder is 72°. A fire department's longest ladder is
Julli [10]

Answer:

The maximum safe rescue height is   104.6 feet above the height of  the ground.

Step-by-step explanation:

Consider a triangle ABC where C is the point where the rescue ladder is standing and  AB be the building  and Ladder making an angle of 72° as shown.

We have to find the height of the building.

Let x be the height of building

Using Trigonometric ratio,

\sin C=\frac{\text{Perpendicular}}{\text{Hypotenuse}}

\sin 72^{\circ}=\frac{AB}{BC}

\sin 72^{\circ}=\frac{x}{110}

x=110 \times \sin 72^{\circ}

x=104.6

So, the maximum safe rescue height is   104.6 feet above the height of

the ground.

I need help ASAP please
trapecia [35]

Answer:

B

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = \frac{1}{\sqrt{2} } , then

cos45° = \frac{adjacent}{hypotenuse} = \frac{3}{c} = \frac{1}{\sqrt{2} } ( cross- multiply )

c = 3\sqrt{2}
