Then you'll need to get started on it pretty soon.
Just take it slow and easy, and remember your order of operations (or PEMDAS).
First look through it and do any multiplications and divisions that you find.
Then do the additions and subtractions.
I just gave it a quick scan and I came up with 26. I dont know if it's correct.
Get to work. You can do this !

A plot of the points A(-2, 11), B(5, 7), C(1, 0) is given by the option;

  • D

  • The triangle is a right triangle given that (AC)² = (AB)² + (BC)²

  • The area of the ∆ABC is 32.5 square units.

  • Sum of the squares of the lengths of the legs of the triangle = <u>130</u>

  • Square of the length of the hypotenuse of the triangle = <u>130</u>

<h3>How can ∆ABC be proven to be a right triangle from its dimensions?</h3>

The coordinates of the vertices of the triangle are;

A = (-2, 11), B = (5, 7), C = (1, 0)

Therefore, on the coordinate plane, we have;

The highest and leftmost point of the triangle is the vertex, <em>A</em>

The second highest and rightmost point of the triangle is the vertex, <em>B</em>

The<em> </em>vertex of the triangle that is midway between <em>A </em>and <em>B </em>and the lowest vertex of the triangle is the vertex <em>C</em>

  • The<em> </em>correct<em> </em>option that shows the points ABC and triangle ABC is the option <em>D</em>.

The lengths of the sides of the triangle are;

AB = √((-2 - 5)² + (11 - 7)²) = √(65)

BC = √((5 - 1)² + (7 - 0)²) = √(65)

AC = √((-2 - 1)² + (11 - 0)²) = √(130)

Therefore;

(AC)² = 130 = (AB)² + (BC)² = 65 + 65

Which gives;

  • (AC)² = (AB)² + (BC)²

Therefore;

  • ∆ABC is a right triangle, from the definition of a right triangle.

The legs of ∆ABC are AB and BC

AC is the hypotenuse of ∆ABC

The area of ∆ABC is therefore;

Area = (1/2) × AB × BC

Which gives;

Area of ∆ABC = (1/2) × √(65) × √(65)

√(65) × √(65) = 65

  • Area of ∆ABC = (1/2) × 65 = 32.5

(AB)² + (BC)² = 65 + 65 = 130

Therefore;

  • Sum of the squares of the lengths of the legs of the triangle = 130

(AC)² = 130

  • Square of the length of the hypotenuse of the triangle = 130
