Yogita Ingle 6 years, 2 months ago

First find the HCF of 1620 and 1725

1725 = 1620 × 1 + 105

1620 = 105 × 15 + 45

105 = 45 × 2 + 15

45 = 15 × 3 + 0

HCF ( 1725 , 1620 ) = 15

Now we have to find HCF of 15 and 255

255 = 15 × 17 + 0

HCF ( 15 , 255 ) = 15

Therefore ,

HCF ( 1620 , 1725 , 255 ) = 15

Vinit Kumar Dubey 6 years, 2 months ago

Given, ABCD is a square X and Y points on side BC and AD and AY=BX We have to prove angle XAY= angle YBX Proof :In triangle ABY and triangle BAY AY=BX (given) angle BAY=angle ABX=90° AB=AB Thus, By SAS congruency triangle ABY congruent to triangle ABX Thus, By C.P.C.T Angle BAX=angle ABY Now, angle XAY=90°-angle BAX, and angle YBX=90°-angle ABY= 90°- angle BAX Hence ,we can say that angle XAY=angle YBX Prooved.
