Answer:
x=15
Step-by-step explanation:
Hey There!
So what we want to do is inverse operations from the formula of area of a triangle
The area is equivalent to
h=height
b=base
now we setup an equation with what we are given
we are given A (area) and h(height)
so the equation looks like...
now we solve for b (x)
step 1 multiply each side by 2
75x2=150
/2x2 cancels out
now we have
150=10b
step 2 divide each side by 10
150/10=15
10/10 cancels out
b=15
We can conclude that the base (aka x) is equal to 15
