Answer:
(5 √3) / 4
Explanation:
We have an angle of 60 and right-angle (90°).
Total number of angles in a triangle add up to 180°.
the angle at the bottom of that triangle (the one below the 5) must be
180 - 90 - 60 = 30°
We can use the Sine rule, which states (in our question) (x / SIN 30) = (5 / SIN 60).
Multiply both side by SIN 30.
we now have x = (5 multiplied by Sin 30) / Sin 60
= ( 5 X 0.5) / (√3 / 2)
= (5 √3 ) / 4
This is value of x.
