The parallelogram shown below has an area of 140 units

What is the missing base?

14 units

Step-by-step explanation:

Area=b×h, where b is the unknown base and h=10

140=b×10, b=14 units

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
