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

How to find an equation for a line through two given points?​
xz_007 [3.2K]

Answer:

The equation of the line is: y = 0.6x + 0.6

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Two points:

We have these following two points in this exercise:

x = -6, y = -3, so (-6,-3)

x = 4, y = 3, so (4,3)

Finding the slope:

Given two points, the slope is given by the change in y divided by the change in x.

Change in y: 3 - (-3) = 3 + 3 = 6

Change in x: 4 - (-6) = 4 + 6 = 10

So

m = \frac{6}{10} = 0.6

Then

y = 0.6x + b

Finding b:

We replace one of the points in the equation to find b. I will use (4,3).

y = 0.6x + b

3 = 0.6*4 + b

2.4 + b = 3

b = 0.6

The equation of the line is: y = 0.6x + 0.6

How do you find the legs of a right triangle when only given the hypotenuse?
tangare [24]

Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

4 \sqrt{2}  =  \sqrt{32 }  \\    \sqrt{32} ^{2}  = 32

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be <em><u>4</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>both</u></em><em><u> </u></em><em><u>x</u></em><em><u> </u></em><em><u>and</u></em><em><u> </u></em><em><u>y</u></em>
