This is a division problem.
Divide 2 3/5 by 1/8.
First, write 2 3/5 as an improper fraction.
Then divide the fractions.

(2 3/5) / (1/8) =

= (13/5) / (1/8)

= 13/5 * 8/1

= 104/5

= 20 4/5

There were 20 1/8-inch thick slices and one thinner slice at the end.

13/5 * 8/1 = 104/5 = 20 4/5

104/5 = x/8

5x = 832

X = 166.4

166.4/8 = 20.8

20.8 pieces

What is the measure of each interior angle of a regular 20- hon?

PolarNik [594]

Answer:

162°

Step-by-step explanation:

To find the measure of an interior angle in a regular n-gon, we use the formula:

(n - 2)(180) / n

We substitute 20 in for n to get:

(20 - 2)(180) / 20

And simplify:

(18)(180) / 20

(18)(9)

162°

Answer:

Therefore,

IU = 7x = 7×1 = 7 units

Step-by-step explanation:

Given:

Δ TRU and Δ IRU are right angle triangle.

TU = 2x + 5

IU = 7x

RU = common Hypotenuse

To Find:

IU = ?

Solution:

In right angle triangles Δ TRU and Δ IRU we have sine identity as

$\sin (\angle TRU)= \frac{\textrm{side opposite to angle TRU}}{Hypotenuse} \\\\\\and\\\sin (\angle IRU)= \frac{\textrm{side opposite to angle IRU}}{Hypotenuse}$

Now,

∠ TRU = ∠ IRU = 19° ............Given

Substituting the given values in it we get

$\sin 19=\frac{2x+5}{RU} \\and\\\sin 19=\frac{7x}{RU} \\\textrm{on equating both the equation we get}\\\\7x=2x+5\\7x-2x=5\\\\5x=5\\\\x=\frac{5}{5} \\\\x=1$

Therefore,

IU = 7x = 7×1 = 7 units
