Angles Part 1

A positive acute angle is divided into two parts whose tangents are 1/2 and 1/3. Show that the angle is (pi)/(4).

The object at rest suddenly explodes into three parts with the mass ratio 2:1:1 . The parts of equal masses move at right angles to each other with equal speeds. What is the speed of the third part after the explosion?

An explosion blows a rock into three parts. Two parts go off at right angles to each other . These two are 1 kg first part moving with a velocity of 12 ms^(-1) and 2 kg second part moving with a velocity of 8 ms^(-1) . If the third part flies off with a velocity of 4 ms^(-1) . Its mass would be

Identify each of the given pair of angles as alternate angles, co-interior angles or corresponding angles or none of these in the given figure: angle1, angle6

If two angles of a triangle are tan^(-1) ""(1)/(2) and tan^(-1)"" (1)/(3) . Then the third angle is

If A,B,C are the angles of a non right angled triangle ABC. Then find the value of: |[tanA,1,1],[1,tanB,1],[1,1,tanC]|
