The answer is 4 because 'of' mean multiply so you do 4/5 times 5 which is 4
Answer:
For E, each angle is 60° because its an equilateral triangle.
F is 45° for x, 135° for y, lastly z is 22.5°
Given:
Bl parallel to RA.
To find:
The value of x.
Solution:
In triangle ATR and ITB,
[Common angles]
[Corresponding angle]
[AA property of similarity]
We know that the corresponding sides of a similar triangle are proportional. So,



On cross multiplication, we get




Therefore, the correct option is C.
The second one, x=(0.18)(23.5)
