u = 10.4 and v = 12
Solution:
In the given 2 sides of a triangle are 60°, 60°.
Sum of all the angles of a triangle = 180°
60° + 60° + third angle = 180°
⇒ third angle = 180° – 60° – 60°
⇒ third angle = 60°
All angles are equal, therefore the given triangle is an equilateral triangle.
⇒ All sides are equal in length.
⇒ v = 12
The line drawn from the top angle divides the triangle into two equal parts
and the line is perpendicular.
12 ÷ 2 = 6
Using Pythagoras theorem,

⇒ u = 10.4
Hence, u = 10.4 and v = 12.

Answer:
x = 9
Step-by-step explanation:
Corresponding segments are proportional, so ...
(2x -8)/5 = (x -3)/3
3(2x -8) = 5(x -3) . . . multiply by 15
6x -24 = 5x -15 . . . . eliminate parentheses
x = 9 . . . . . . add 24-5x
