Answer:

2 v 13, 2 Square root 13

Step-by-step explanation:

there's 2 right triangles

a)

10^2 = 6^ + a^2

100 - 36 = a^2

64 = a ^2

a = 8

--------------------------------------------

now we know the base of the right triangle = 8

and also the base of the left one = 4

8 + 4 = 12

--------------------------------------------

now find x

b)

x^2 = 6^2 + 4^2

x^2 = 36 + 16

x^2 = 52

x = (square root) 52

x = 2 v 13     <---- "v = square root"

<h2>Question :- Find the unknown side . </h2>

Instructions :- Simplify the answer if there is square root

<h2>Given :- </h2>
  1. Two triangles
  2. Total length of the base 12
  3. First triangle dimensions
  • 10 as it's hypotenuse
  • 6 as it's perpendicular

<h2>Answer:- X = ✓ 52 = 7.2</h2>

<h2>Explanation:- </h2>

<h3>Formula :- </h3>

hypotenuse² = perpendicular²+base²

<h3>Solution:- </h3>

First triangle:-

{h}^{2}  =  {p}^{2}  +  {b}^{2}  \\  {10}^{2}  =  {6}^{2}  +  {b}^{2}  \\ 100 = 36 +  {b}^{2}  \\ 100 - 36 =  {b}^{2}  \\ 64 =  {b}^{2}  \\ 8 =  b

Second triangle

  1. perpendicular = 6
  2. hypotenuse = X ( to Find )
  3. base = 12-b = 12-8= 4

{h}^{2}  =  {p}^{2}  +  {b}^{2}  \\  {x}^{2}   =   {6}^{2}  +  {4}^{2} \\  {x}^{2}  = 36 + 16 \\  {x}^{2}  = 52 \\ x =  \sqrt{52}  = 7.2 \\ x = 7 \:  \: approx

Answer:

y = -4

Step-by-step explanation:

First, let's find the slope. Since the line is horizontal, it's slope has to be 0 (this is because slope = rise/run, there is no "rise" in a horizontal line therefore the slope is 0)

Now, we need to find the y-intercept. This is where the line intercepts the y-axis. Looking at the graph, the line intercepts the axis at (0,-4), therefore the y-intercept is -4.

The equation would be:

y=0x-4

y=-4

Solve each system of equation using any method.<br> 7 x + y = 5 2x - y = 4
nexus9112 [7]

Answer:

x = 1

y= -2

Step-by-step explanation:

to solve this system of equation , simultaneously using the substitution method

we say let

7 x + y = 5 ............................................. equation 1

2x - y = 4 ................................................... equation 2

from equation 2

2x - y = 4 ................................................... equation 2

2x - 4 = y

y = 2x -4.......................................................... equation 3

put the value of the y = 2x -4 into equation 1

7 x + y = 5 ............................................. equation 1

7x + 2x - 4 = 5

9x-4 = 5

9x = 5 + 4

9x = 9

divide both sides by the coefficient of x which is 9

9x/9 = 9/9

x = 1

substitute the value of x = 1 into equation 3

y = 2x -4.......................................................... equation 3

y = 2(1) -4

y = 2 - 4

y = -2

to check if you are correct put the value of x and y into any of the equations and you will see that the left hand side will be equal to the right hand side.

2x - y = 4 ................................................... equation 2

2(1) -(-2) = 4

2 + 2 = 4

4=4................................... proved

Plz answer last question and im lost!
harkovskaia [24]

Answer:

\pi radian

Step-by-step explanation:

We know that angle for a full circle is 2\pi

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of  angle for a full circle = 1/2 * 2\pi = \pi

Thus, answer is \pi radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as \pi radian.
