The triangle shown below has an area of 10 units. find x.

The value of x (which is also the height of this triangle) is x = 5 units.

Step-by-step explanation:

The formula for the area of a triangle of base b and height h is

A = (1/2)(b)(h).

Here A = 10 units² = (1/2)(4 units)(x).

Multiplying both sides by 2 yields    20 units² = (4units)(x), and thus

       20 units²

x = = 5 units

         4 units

The value of x (which is also the height of this triangle) is x = 5 units.

x = 12

y = 15
