Mathematics

3x - 14 = 2x + 25

      +14      +14

3x = 2x + 39

-2x     -2x

x= 39

therefore x is 39. If you want to find the exact angel, just substitute 39 into x, solve for it and it should give you the exact angel.

Hope I helped :)

3x-14

x=

3 times 22.5 equals 89 if you do 89 mius 14 you will get 75.

on the bottom

if you do 2 times 25 you get 50 all you have to do is add the 50 and 25 to get 75. the angles are have the same value.

Triangle F G E is shown. Angle F E G is a right angle. The length of hypotenuse F G is 18.6 inches and the length of F E is 12 i
Delicious77 [7]

Answer:

Measure of ∠FGE is 40.2°.

Step-by-step explanation:

Refer to the attachment.

Consider ΔFGE. Given that ∠FEG = 90° and ∠FGE is x°.

To find the value of ∠FGE use trigonometric ratios.

Use sine ratio to find the value of ∠FGE.

\sin \theta=\dfrac{opposite\:side}{hypotenuse\:side}

Rewriting it in terms of x° as follows,

\sin x=\dfrac{opposite\:side}{hypotenuse\:side}

Now find the opposite and hypotenuse side of the angle ∠FGE.

So opposite side of ∠FGE is FE and hypotenuse side of ∠FGE is FG.

Substituting the values,

\sin x=\dfrac{FE}{FG}

Given that length of FE is 12 inch and FG is 18.6 inch.

Substituting the value,

\sin x=\dfrac{12}{18.6}

To find the value of x, taking inverse sin.

x=\arcsin \left(\dfrac{12}{18.6}\right)

Calculating the value,

x=40.17

Rounding to nearest tenth the value of angle is 40.2

Therefore measure of ∠FGE is 40.2° .

. Mr. Donut wants to paint a donut on the wall of his restaurant. The diameter of the outside edge of the donut will be 22 inche
KATRIN_1 [288]

Answer:

The area needed to be painted is approximately 301.44 square inches.

Step-by-step explanation:

The shape of a donut is represented by two concentrical circles, whose area is described by the following formula:

A =A_{g}-A_{s} (Eq. 1)

Where:

A - Total area of the donut, measured in squared inches.

A_{g} - Area of the greater circle, measured in square inches.

A_{l} - Area of the lesser circle, measured in square inches.

By using the definition of the area of the circle, we expand the equation above:

A = \frac{\pi}{4}\cdot D^{2}_{ext} - A_{s} (Eq. 1b)

If we know that \pi = 3.14, D_{ext} = 22\,in and A_{s} = 78.5\,in^{2}, the area needed to be painted is:

A = \frac{(3.14)\cdot (22\,in)^{2}}{4}-78.5\,in^{2}

A \approx 301.44\,in^{2}

The area needed to be painted is approximately 301.44 square inches.
