The value of x as required in the task content is; 4.5.
<h3>What is the value of X?</h3>
From the task content, it can be deduced that the larger and smaller triangles are congruent.
Hence, the ratio of their corresponding sides are equal and the value of X can be computed as follows;
(x+6)/(2x+6) = 21/30
42x + 126 = 30x +180
12x = 180 - 126
12x = 54
x = 54/12 = 4.5
