If A(-1,3), B(4,4), C(8,1) , then classify ABC as scalene, isosceles, or equilateral.
Gala2k [10]
For this case we use the formula of distance between points.
 We have then:
 d = root ((x2-x1) ^ 2 + (y2-y1) ^ 2)
 For AB:
 AB = root ((4 - (- 1)) ^ 2 + (4-3) ^ 2)
 AB = 5.099019514
 For AC:
 AC = root ((8 - (- 1)) ^ 2 + (1-3) ^ 2)
 AC = 9.219544457
 For BC:
 BC = root ((8-4) ^ 2 + (1-4) ^ 2)
 BC = 5
 We observe that it has three sides with different dimensions, therefore, the triangle is scalene.
 Answer:
 
Scalene

Find the x will name brainlist
Alenkasestr [34]

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Find x.

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

To solve these type of problems you need to use the pythagoras theorem ⇨ Hypotenuse² = Base² + Altitude².

Here,

  • Altitude = 1.6 cm.
  • Base = 1.2 cm
  • Hypotenuse = x

Now, let's solve for x.

Hypotenuse² = Base² + Altitude²

x² = (1.2)² + (1.6)²

x² = 1.44 + 2.56

x² = 4

x = √4

x = <em><u>2</u></em><em><u>.</u></em>

  • So, the value of x is <em><u>2</u><u> </u><u>cm.</u></em>

<h3><u>NOTE</u><u> </u><u>:</u><u>-</u></h3>
  • Pythagoras theorem can be used only in the cases of right-angled triangles. Here, it's given that the triangle is right angled so we can use this theorem.
  • To solve the squares if decimals, take them as whole numbers & then just add the decimal points. For example, ⇨ for (1.2)², take it as 12² , then multiply 12 by 12, you'll get 144. Now, add the decimal place accordingly ⇨ 1.44 . So, (1.2)² = 1.44.
