Option b is the correct answer
Answer:
sin(2θ) = 24/25
Explanation:
In order to find the value of sin 2θ, first, recall the double-angle formula for sine.
From the right-triangle:
Substitute these values into the double-angle formula obtained earlier.
The exact value of sin(2θ) is 24/25.
Answer: angle 2 is supplementary to angle 1
Since the two triangles are similar angle G = angle J, angle H = angle K, angle I = angle L
Therefore, angle J = 180 - 60 - 25 = 95 degrees.
