What is the image of the point (–3, 4) after a rotation of 90° counterclockwise about the point (–3, 0)?
Snowcat [4.5K]
Initially, the point (-3,4) is in the second quadrant of the cartesian plane. If the rotation is about point (-3,0) at 90 degrees, you find a point that when connected to (-3,4) makes two lines perpendicular to each other. Since the direction is counterclockwise, you move 3 points to the left, then 4 points down. That would be (-7,0). The answer is A.

Is a square a rectangle
hram777 [196]

Answer:

Yes

Step-by-step explanation:

Hi there,

Yes, the definition of a rectangle is "a plane figure with four straight sides and four right angles." A square has all of these, so by definition, a square is a rectangle.

But be careful! A square IS a rectangle but a rectangle IS NOT a square!

Hope this helps! Stay safe!

Solve the triangle.<br> A = 32°, a = 19, b = 14
Paha777 [63]

Answer:

A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36

Step-by-step explanation:

We have two sides of the triangle and we have an angle.

A = 32 °, a = 19, b = 14

We use the sine theorem to find the angle B.

We know that according to the sine theorem it is true that:

\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}

\frac{sin(32\°)}{19}=\frac{sin(B)}{14}

sin(B)=14*\frac{sin(32\°)}{19}\\\\B=Arcsin(14*\frac{sin(32\°)}{19})\\\\B=22.98\°

We know that the sum of the internal angles of a triangle is always equal to 180.

So:

C=180-32-22.98\\\\C=125.02\°

Finally we find the c side

\frac{sin(A)}{a}=\frac{sin(C)}{c}

\frac{sin(32\°)}{19}=\frac{sin(125.02)}{c}

0.02789=\frac{sin(125.02)}{c}

c=\frac{sin(125.02)}{0.02789}\\\\c=29.36

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9
castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

{a}^{2}  =  {b}^{2}  +  {c}^{2}

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

{10}^{2}   =  {5}^{2}  +  {x}^{2}

{x}^{2}  =  {10}^{2}  -  {5}^{2}

{x}^{2}  = 100 - 25

{x}^{2}  = 75

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you
