In the following diagram if AB=BC and CD=DE, find the value of Angle GCF?

Answer :: 45 degrees

solution ,, <BCA=a ,, <DCE=b

==<BGA=<CGF=90-a and similarly <DFE=<CFG=90-b

now in triangle CGF , <GCF=180-(90-a)-(90-b) <GCF=a+b

Also <BCD=90=2*(a+b) {given}

==<GCF=a+b=45

let BAC=a=BCA and DEC=DCE=b then CBG=(180-2a)-90=90-2a similarly CDF=90-2b this gives CGF=90-2a+a=90-a and similarly CFG=90-b also GCF=90-a-b . ......(1) from triangle GCF 90-a+90-b+90-a-b=180 or a+b=45 substitute in (1) angle GCF=45

If the star has an outside perimeter of 50, and the pentagon has a perimeter of 30, what is AB + BC + CD + DE + EA = ??

In a Right angle triangle ABC

AB=3,AC=4 & BC=5

at BC,E is middle point and D is altitude AD

Find distance DE=?

it is not a difficult question everyone who know maths ... Can YOU solve it easily ...... solve it in one line...........or in second..........?

The figure shows an isosceles triangle with AB = BC. The line DE cuts AC extended at F. If AD=5, CE=3 and EF=8 find DE.

ABC has a right angle at B with AC=60, AE=52 and CD=39. Find the length of DE?

If lengths of sides AB, BC and AC of a right angle triangle are in a geometric progression, what is the ratio between AC and AB?
