The formula for the area of a triangle is a = bh, where b is the length of the base and h is the height. the equation solved for h is h = . find the height of a triangle that has an area of 30 square units and a base measuring 12 units. 3 units 5 units 8 units 9 units

5 units

Step-by-step explanation:

1/2x12=6

30/6=5

5=h

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
