Cos ( 37 ) = 30 / x

0.7986 = 30 / x

x = 30 / 0.7986

x = 37.5657

x = 37.5660

x = 37.5700

x = 37.6000

x = 37.6 yard

Answer:

<h3>Value of x is 30° </h3>

<h2>Step-by-step explanation: </h2>

<h3>Step 1: Find value of x by using the trigonometric ratio cosine of x. Here, given that adjacent side is 16 and hypotenuse is 18 </h3><h3>cos x° = adjacent side/hypotenuse = 16/18 = 8/9 </h3>

<h3>x° = cos inverse(8/9) = 27.12° = 30° (Rounded off to nearest ten) </h3>

Simplify 18-2[x + (x - 5)].<br> O8-4x<br> 28 - 4x<br> 28 - 2x
densk [106]

Answer:

28-4x

Step-by-step explanation:

Step 1: Open most inner bracket and simplify

=18-2(x+x-5)

=18-2(2x-5)

Step 2: Expand brackets by multiplying 2 in and simplify

=18-2(2x)-2(-5)

=18-4x+10

=28-4x

Therefore the answer is 28-4x

WILL MARK BRAINLIEST Which expression is equivalent to −1.3 + (−4.9 ) + (−2.6) ?
Furkat [3]
You can remove the first plus sign to give:
-1.3 -4.9 [ because + x - = - ]
and by the same rule you can remove the the second plus sign to give
-1.3 -4.9 - 2.6
That means option b is out because it is positive. 
straight away we can see that option D. equals the result, so it is in the running, so now can we eliminate c and a?
we can eliminate a because the  minus ign outside the bracket multiplied by -4.9 inside the bracket produces + 4.9, which is not the answer, so that only leaves c. 
once again, a plus sign outside the bracket does not produce -4.9 when muliplied by  4.9 inside the bracket inside option c, so we can eliminate option c.
