PQ has endpoints at PH(7, -11) and Q(-5,-8). Find the slope of PQ

shusha [124]

Slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
slope beteen (7,-11) and (-5,-8) is

(-8-(-11))/(-5-7)=(-8+11)/(-12)=3/-12=-1/4

slope=-1/4

4. An equilateral triangle has a perimeter of 60 cm. Find the exact<br> altitude of the triangle.

taurus [48]

Step-by-step explanation:

<h2>GIVEN:-</h2>

The Perimeter of Equilateral triangle = 60cm

<h2>UNDERSTANDING THE CONCEPT:-</h2>

According to the question,

To find the height of the triangle,

Perimeter of Equilateral triangle = Area of Equilateral triangle.

<h2>FORMULA USED:-</h2>

$60 = \frac{ \sqrt{3} }{4} a {}^{2} \\$

<h2>REQUIRED ANSWER:-</h2>

$60 \times 4 = \sqrt{3a {}^{2} }$

$a {}^{2} = 240 \sqrt{3} \\$

$a = 120 \sqrt{3} cm$

<h3>SO, The Exact height of the triangle is 120√3cm.</h3>
