The area of a triangle formal is base times height divided by 2. So 9x 12 which equals 108 then you divide that by 2 which equals 54 and the unit is cm^2
Step-by-step explanation:
y = -0.5x + c
When x = 4, y = -7.
=> (-7) = -0.5(4) + c, c = -5.
Therefore the equation is y = -0.5x - 5.
Simplify the equation using cross-multiplication
400tan(29)=h
switch the sides of the equation
h=400tan(29)
evaluate
h=354.857
