Answer:
72 Centimeters
Explanation:
Formula for area: 1 /2 b · h
b = Base (18 cm.)
h = height (8 cm.)
1 / 2 Base: 9
height: 8
9 · 8 = 72
Therefore the area of the triangle is 72 centimeters
Using the "X" Axis and the "Y" Axis like the last question you asked, Point E would be standing at (6,1)
find the surface area and then round it
Answer:
<em>Standard line equation</em><em>:</em><em> </em>
y=ax+b
The point (5,1) is on the line. so :
1=a(5)+b → 1=5a+b
The point (1,-5) is also on the line. Then :
-5=a(1)+b → -5=a+b
Subtract the two equations in terms of a and b. we have:
6=4a → a=3/2 , b=-6.5
<em>y=1.5x-6.5</em>
