Answer:

[tex]4 \sqrt{11} [/tex]

Step-by-step explanation:

According to Pythagoras Theorem,

[tex] {(hypotenuse)}^{2} - {height}^{2} = {(base)}^{2} [/tex]

[tex] = > {24}^{2} - {20}^{2} = {x}^{2} [/tex]

[tex] = > \: {x}^{2} = 576 - 400[/tex]

[tex] = > {x}^{2} = 176[/tex]

[tex] = > x = \sqrt{176} [/tex]

[tex] = > x = \sqrt{2 \times 2 \times 2 \times 2 \times 11} [/tex]

[tex] = > x = 2 \times 2 \sqrt{11} [/tex]

[tex] = > x = 4 \sqrt{11} (ans)[/tex]

Answer:

Step-by-step explanation:

According to figure,

54° + 3x+36° = 180° [Linear pair]

=> 3x + 90 = 180

=> 3x = 180 - 90

=> 3x = 90

[tex] = > x = \frac{90}{3} [/tex]

=> x = 30 (Ans)

Answer:

x=30

Step-by-step explanation:

cuz that line is 180 degrees and using algebra you can subtract 54 from both sides and get 126 then u have to subtract the 36 from both side to geth 90 and then divide the 3x to get x by itself which would leave u with 30 so x=30

Answer:

2 square cm

Step-by-step explanation:

Given :

A square is inscribed in a circle whose radius is r = 1 cm

Therefore, the diameter of the circle is 2 r = 2 x 1

                                                                      = 2 cm.

So the diagonal of the square is 2r.

Using the Pythagoras theorem, we find each of the side of the triangle is [tex]$r \sqrt 2$[/tex].

Therefore, the area of the square is given by [tex]$\text{(side)}^2$[/tex]

                                                                         = [tex]$(r\sqrt 2)^2$[/tex]

                                                                         [tex]$= 2 r^2$[/tex]

                                                                         [tex]$= 2 (1)^2$[/tex]

                                                                         [tex]$=2 \ cm^2$[/tex]

Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.

Hello! I believe the answer is A. 30+0.25p=60.

Elijah has to pay a facility charge which is 30$. So we can go ahead and write that down! He has 60$ to spend, but he has to pay $0.25 per paintball. So we write that as 30+0.25p=60!! If you have any questions comment doen below!

Step-by-step explanation:

4x+12=40

-12

4x=28/4

Answer:

x =7

Step-by-step explanation:

4x + 12 = 40

4x + 12 - 12= 40 -12

4x = 28

4/4= 28/4

x= 7

Answer:

20

Step-by-step explanation:

use pythagorean theorem:

[tex]12^{2}[/tex] + [tex]16^{2}[/tex] = [tex]c^{2}[/tex]

144 + 256 = [tex]c^{2}[/tex]

400 = [tex]c^{2}[/tex]

[tex]\sqrt[ ]{400}[/tex] = c

20 = c

Answer:

A - 23ft

Step-by-step explanation:

Pythagorean theorem: 12^2 + 20^2 = X^2.

X^2 = 544. X = sqrt(544) which is around 23ft

Answer:

x=0

Step-by-step explanation:

Let's solve your equation step-by-step.

6x+x=10x

Step 1: Simplify both sides of the equation.

6x+x=10x

(6x+x)=10x(Combine Like Terms)

7x=10x

7x=10x

Step 2: Subtract 10x from both sides.

7x−10x=10x−10x

−3x=0

Step 3: Divide both sides by -3.

−3x/−3 = 0/−3

x=0

Now you can figure out which one is the best solution

Answer: 18

Step-by-step explanation:

Answer:

Angle B: 28 degrees

Side a: 27.6

Step-by-step explanation:

Angle B:

180-112-40=28

Side a:

sin 28/14 = sin 112/a

a = sin 112(14)/sin 28

a = 27.6

Answer:

The measure of angle B is 69°.

Step-by-step explanation:

All angles of the triangle should add up to 180°, so you add angle A and angle C together, and then subtract that number from 180.

49 + 62 = 111

180 - 111 = 69

69°

sin θcos θ

hope it is helpful to you

Answer:

sin A cos A

Step-by-step explanation:

[ I don't know to type angle theta here so assume A as theta]

As , sin A= p/ h

cos A= b/ h

so,

sinA cosA = p/ h × b/h

= pb/ h^2 ( which is not equal to 1 )

Tip; you can easily verify other relations expressing trigonometric ratios in terms of p,b & h and further simplifying..
