Answer:

Step-by-step explanation:

here is how you find the answer

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

now apply the above rules to the given triangle

where we are given the angle of 30°  and the Adj side of 27

y is the Hyp of this triangle and x is the Opp side of this triangle, now plug in the given values  as follows

so use CAH   Cos(30) = 27 / Hyp

Hyp = 27 / Cos(30)

Hyp = 27 / (\sqrt{3} / 2)

Hyp = 27 * 2 /  \sqrt{3}

Hyp = 54 / \sqrt{3}

y = 54 / \sqrt{3}

use SOH, since we know the exact value for the Hyp from above

Sin(30) = Opp / ( 54 / \sqrt{3}  )

Sin(30) * 54 / \sqrt{3}  = Opp

1/2 * 54 / \sqrt{3}  = Opp

27 / \sqrt{3}  = Opp

x = 27 / \sqrt{3}

A point lies in quadrant 2. If it is rotated 180 degrees counterclockwise, which quadrant will the point come to rest?
NeTakaya
A point (a, b) in the second Quadrant, is any point where a is negative and b is positive.

For example (-3, 5), (-189, 14) etc are all points in the 2.Quadrant

Rotating a point P(x, y) in the second Quadrant 180° counterclockwise, means rotating 180° counterclockwise about the origin, which maps point P to P'(-a, -b) in the fourth Quadrant.

CAN SOMEONE HELP PLZ AND EXPLAIN BEC IF DONT DO GOOD I CANT GO TO MY DADS HOUSE THIS WEEK END
Galina-37 [17]
Hello!

6.
Since the area is that of a square, you know that all side lengths are the same. 

Area is base times height (A = bh), but since base and height are the same for a square, you get the formula A = a².

A = a^{2}
144 = a^{2}
\sqrt{144} = a
12 = a

The length of the side of a square with an area of 144 in² is 12 in.

7.
Rational number.

8.
This is a right triangle; use the Pythagorean Theorem to find missing lengths of right triangles. Pythagorean Theorem: a² + b² = c², where c is the hypotenuse of the triangle.

Plug in your leg lengths:

a² + b² = c²
8² + x² = 21²
64 + x² = 441
x² = 377
x = 19.4

What is the solution to this inequality? x - 8 > -3 A. X>-11 B. X<-11 C. X<5 D. X>5
erik [133]

Answer

D. X>5

Step by step explanation

x - 8 > -3

Here we have to find the value of x.

Add 8 on both sides, we get

x - 8 + 8 > -3 + 8

x > 5

Thank you.
