KengaRu [80]

Answer:

27 inches

Step-by-step explanation:

To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.

The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:

cos(48) = height / diagonal

0.6691 = 18 / diagonal

diagonal = 18 / 0.6691 = 26.9 inches

Rounding to the nearest inch, the diagonal of the canvas measures 27 inches

Help me plssss <br> its for a math test and im braindead atm
Gwar [14]

Answer:

5/8

Step-by-step explanation:

3/8 + 1/4

To add these fractions, you need a lowest common denominator.  Both 4 and 8 "go into" 8, so the lowest common denominator is 8.

In order to change the denominator 4 to 8, you need to multiply both the numerator and the denominator by 2.  So, 1/4 becomes 2/8.

Now, the problem is 3/8 + 2/8.  

You can add the numerators, because the denominator is the same for each fraction.

3/8 + 2/8 = 5/8

AB= 4x + 7 and BC = 20x - 5 <br> AB ~= BC
Mariana [72]

The value of the variable x is 3/4

<h3>What are congruent segments</h3>

Congruent segment are segments with equal or congruent lengths.

From the information given, we have that line AB is approximately equal to line BC. This is represented as;

AB = BC

Where;

  • AB = 4x + 7
  • BC = 20x - 7

Now, let's equate the expressions

4x + 7 = 20x - 5

collect like terms

4x - 20x = - 5 - 7

- 16x = - 12

Make 'x' the subject of formula

x = -12/-16

x = 3/4

Thus, the value of the variable x is 3/4
