Question

This is a similar triangle please find the missing length. (?)

Answer 1

33

Explanation:

`(HG)/(FG) =(RQ)/(PQ)`, insert given values

`(?)/(36)=(77)/(84)`, cross multiply

84*?=36*77

84*?=2772, divide both sides by 84 to get ? by itself

?=33

Answer 2

33

Explanation:

In ΔPQR,

length of side=

77= 7×11

84= 12

Similarly, In ΔFGH

length=

36=3×12

so, the other side= 3×11= 33
