In this case, multiplying the two denominators of the fractions give 34 as the correct LCD.
The answer is y<3. Hope this helps. (correct me if im wrong and sorry for the bad handwriting)
Answer:
Solution given:
AB parallel BH parallel CH
1.
In triangle ∆AFD ,∆BGD ,∆CHD
<AFD=<BGD=<CHD
[being corresponding angle]
<DAF=<DBG=<DCH
[being corresponding angle]
<D is common for all.
So
∆AFD ~∆BGD ~∆CHD
[By A .A .A. axiom]
