‘in’ the public interest is the correct usage. For the second blank, ‘those’ will be used as people are being talked about. It is in the public interest to expedite cases in which those in public life face serious charges.
If tan α = 1/2, tan β = 1/3, then find α + β.
Find the simplified value of:
(tan 40 º + tan 20 º )/(1 - tan 40 º tan 20 º)
In a right triangle ABC, angle B = 90°. If tan A = 3/4 and the length of the hypotenuse is 25 cm, find the area of the triangle.
