Question

A triangle has an area of 10 units 2 square

Answer 1

Answer:

Step-by-step explanation:

olve the line equation for y

:

y = -ax/2 +5

:

therefore, the y-axis intercept is 5

:

area of triangle = (1/2) * base * height

:

(1/2) * base * 5 = 10

:

base = 4 which is the x-axis intercept

:

-a(4)/2 +5 = 0

:

-2a = -5

:

a = 5/2
