Answer:

Step-by-step explanation:

Using sine rule on triangle ABC as re - shown in the attachment below to get side AC first we have;

∠A = 34°, BC = 164cm, ∠B = 27°, AC = ?

AC/sin 27° = BC/sin 34°

AC/sin 27° = 164/sin 34°

AC = 164 * sin 27° / sin 34°

AC = 74.45/0.5592

AC = 133.14 cm

To get the side 'a', we will use the trig ratio SOH CAH TOA on the right angled ACD.

According to SOH,

sin 61° = a/AC

a = ACsin61°

a = 133.14 * sin 61°

a = 116.45

a ≈ 117 cm

The marked side is approximately 117 cm

Let D be the ordered set of all possible words (not just English words, all strings of letters of arbitrary length) using the La

Lapatulllka [165]

Answer:

To show that A has a supremum is given as,

Step-by-step explanation:

Because A is that the set of all letters from the dictionary starting with the letter 'a'. And as after set A, there'll be a group containing all the opposite words .. so there exists some x during a such every other letter during a comes before it. So it's none aside from a word starting with the letter b therefore the supremum of the set A is letter b.

Answer:

Step-by-step explanation:

you do 2x+2x+6+3x+1 as this is simplified then it is 7x+7=35 then you take away 7 and that is 7x=28 and then u do x=28/7 and then you do x=4 you can check by substituting X

Y’all trynna help me out please

ipn [44]

Answer:

I think it would be $\frac{\sqrt{37}}{\sqrt{77} }$

Step-by-step explanation:

using the saying, "Soh Cah Toa" which means Sine is opposite over hypotenuse Cosine is adjacent over hypotenuse and Tangeant is opposite over adjacent and i am assuming that the angles E and F are 45 which means it is $\frac{DF}{EF}$

How many cubic feet are in 3 cubic yards?

dimaraw [331]

For every cubic yard, it equals to 27 cubic feet.

So, could have this fraction $\frac{27 feet^3}{1 yards^3}$
And we want to convert 3 cubic yards into cubic feet.

We can express 3 cubic yards as $\frac{3 yards^3}{1}$

Now multiply the $\frac{3 yards^3}{1}$ fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.

$\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} = \frac{81 feet^3}{1}$

So, 3 cubic yards to equal to 81 cubic feet.
