The value of x is 8 from the diagram given.
<h3>How do you calculate the sides of similar triangles?</h3>The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.
To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:
x = 120/15
x = 8
Therefore, we can conclude that the value of x is 8.

Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° = =
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
