Answer:
The correct answer is,
the area of given triangle = 1875 square feet
Step-by-step explanation:
Formula:
Area of triangle = bh/2
b - Base and h - height
It is given that,a triangle with a base of 50 feet and a height of 75 feet’
<u>To find the area of triangle</u>
base b = 50 feet and height h = 75 feet
Area = bh/2 = (50 x 75 )/2
Area = 3750/2 = 1875 square feet
Therefore the area of given triangle = 1875 square feet

Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0
