PLS HELP !! Find The Length Of The Third Side. If Necessary, Round To The Nearest Tenth.

Answers

Answer 1
32 I think because of 20+12=32?
Answer 2

Answer: 16

Step-by-step explanation:

Use the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]). A and b are the 2 legs, and c is ALWAYS the hypotenuse.

Plug in the values and solve:

[tex]12^2+b^2=20^2\\144+b^2=400\\b^2=256\\b=16[/tex]

X= root (y-1/y+1) ( make “y” as subject. ) number 19

Answers

Answer:

y = (x² + 1) / (1 – x²)

Step-by-step explanation:

x = √[(y – 1)/(y + 1)]

We can make y the subject of the expression as shown below:

x = √[(y – 1)/(y + 1)]

Take the square of both side

x² = (y – 1) /(y + 1)

Cross multiply

x²(y + 1) = (y – 1)

Clear bracket

x²y + x² = y – 1

Rearrange

x² + 1 = y – x²y

Factorise

x² + 1 = y(1 – x²)

Divide both side by (1 – x²)

y = (x² + 1) / (1 – x²)

Answer:

37.9 degrees

Step-by-step explanation:

Using the law of sines, [tex]\frac{\sin(m\angle C)}{21}=\frac{\sin(47^\text{o})}{25}[/tex]. It follows that [tex]\sin (m\angle C) = \frac{21\sin(47^\text{o})}{25} \approx 0.6143371[/tex]. Therefore, [tex]m\angle C = \sin^{-1}(0.6143371)=37.9^\text{o}[/tex].

Answer: 4.2

Step-by-step explanation:

Here's the formula for how to find the hypotenuse: (a and b are the two legs for the triangle-- it doesn't matter which leg is a and which leg is b, but c MUST be the hypotenuse)

[tex]a^2+b^2=c^2[/tex]

[tex]1.9^2+3.8^2=c^2[/tex]

[tex]3.61+14.44=c^2[/tex]

[tex]18.05=c^2[/tex]

[tex]\sqrt{18.05} =c[/tex]

[tex]c=4.2[/tex]

Solution,
Given from question
h= ? , b=1.9mm and p=3.8mm
We know h^2 = b^2 + p^2
So = (3.8)^2 + (1.9)^2
= 14.44+3.61
=18.05
We know h^2 = 18.05 so
:• h = 4.25mm so
C = 4.25 mm answer

The product of two numbers is 41. One of the numbers
is the complex number 5+4i. What is the other
number?

A. 5-4i
B. 5+4i
C. -5-4i
D. -5+4i
E. 41/5-4i

Answers

Answer:   5 - 4i     (choice A)

===================================================

Work Shown:

x = the other number

(5+4i)*x = 41

x = 41/(5+4i)

x = 41*(5-4i)/( (5+4i)*(5-4i) ) ..... see note below

x = 41*(5-4i)/( 41 )

x = (41/41)*(5-4i)

x = 5 - 4i  

As a way to check, (5+4i)*(5-4i) = 5^2+4^2 = 25+16 = 41

The rule used is (a-bi)(a+bi) = a^2 + b^2

-----------

Note:  I multiplied top and bottom by (5-4i) to get rid of the imaginary term in the denominator.
