If A:B=4:9 and A:C=2:3 , find B:C and A:B:C

If in a !ABC , a^(2)+b^(2)+c^(2)=ac+sqrt3ab then the triangle is

in figure, ABC is an isosceles traingle, right angled at C. therefore a) AB^2 = 2AC^2 b) BC^2 = 2AB^2 c) AC^2 = 2AB^2 d) AB^2 = 4AC^2

In triangle ABC, AB = 5. BC = 9 and AC =7. The value of tan((A-B)/2)/tan((A+B)/2) is

If a+b+c=p and ab+bc+ac=q, find a^(2)+b^(2)+c^(2) .

If a+b+c=p and ab+bc+ac=q, find a^(2)+b^(2)+c^(2) .

Consider the ground state electronic configurations given below and answer the following. A : 1s^2 2s^2 2p^5 , B : 1s^2 2s^2 2p^4 , C : 1s^2 2s^1 , D : 1s^2 2s^2 2p^6 3s^1 , E : 1s^2 2s^2 2p^6 Arrange these configurations in order of increasing I.E.
