The answer will be option a) 2y - x.
Let us take the number as y.
Twice the number will be 2y
Now if we subtract x from it, then the algebraic expression stands like this :
2y - x.
So answer will be option a.
Given:
The figure of a right angle triangle ABC.
AB = x, BC=7, m∠B = 90°, ∠C=16°.
To find:
The value of x.
Solution:
In a right angle triangle,

In triangle ABC,



Multiply both sides by 7.



Therefore, the value of x is about 2 units.
