Answer:

24.75inches

Step-by-step explanation:

The question is incomplete. The complete question is as shown below;

If the answer is not a whole number, it should be entered as a decimal rounded to the hundredths place.

"A photograph with a width of 5.5 inches is being enlarged by a factor of 4 1/2 to make a poster.

The new width of the photograph is_____ inches"

The poster is rectangular in shape. formula for finding the area of a rectangle,

Area A = Length L × width W

Initial width if the photograph = 5.5inches.

If the photograph is enlarged by a factor of 4 1/2, then the new width also increase by that factor since increase in the size of the photograph leads to increase in its area.

New width = 4 1/2 × initial width

New width = 4 1/2 × 5.5

New width = 9/2 × 55/10

New width = 495/20

New width = 24.75inches (to its hundreths place

The degree measure of an acute angle in a right triangle is x. If sinx=2/3, determine if each of the following expressions is al
leonid [27]
<h2> ☞ANSWER☜ </h2>

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.

An acute angle is an angle that measures less than 90 degrees. A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle.

Help idk how to do this ASAP please
Sergio039 [100]

Answer:

The area of ∆DEF = 4.5in²

Step-by-step explanation:

From the above diagram,

∆BAC ~∆DEF

It is important to note that if two triangles are similar, the ratio of their areas is equal or equivalent to the ratio of the areas of their sides

This means for the above question, that

We have the bigger triangle = ∆BAC has a side of 4 in and Area = 8 in²

The small triangle has a side of 3in

Finding the scale factor k = ratio of the sides of both Triangles

k = 4/3

k² = (4/3)²

k² = 16/9

Hence,

Area of ∆BAC/ Area of ∆DEF = 16/9

8in²/Area of ∆DEF = 16/9

We cross Multiply

8 in² × 9 = Area of ∆DEF × 16

Divide both sides by 16

Area of ∆DEF = 72/16

= 4.5in²

Therefore, the Area of ∆DEF rounded to the nearest tenth = 4.5in²

Find the value of x for which ABCD must be a parallelogram.
Inessa [10]
Hey there!

You can tell that the two angles are congruent because of the arc. So make the two angles each other.
3x-17=25-3x. Add 3x to each side. You get 6x-17=25. Add 17 to each side to get 6x=42. Divide each side by 6. You get x=7. So the value of x would be 7.

I hope this helps!

What is the value of x?
alexgriva [62]

Answer:

x = 84

Step-by-step explanation:

If you add up all of the internal angles in ANY pentagon it will be 540, so

x = 540 - (131+108+107+110)
