8 ( 12x + 4 ) = 96x + 32 8 ( 12x + 4 )
= 1920 + 32 OR = 8 ( 240 + 32 )
= 1952 = 1920 + 32
= 1952
8*12x = 96x 96*20 = 1920
8* 4 = 32 12*20 = 240
240*8 = 1920
Step-by-step explanation:
=(1+ sin^2 A/cos^2 A).cos^2 A
=[(cos^2 a+sin^2 a)/cos^2 a].cos^2 A
=[1/cos^2 a] . cos^2 a
=1
From the chord theorem we have:

The HCF is the Highest Common Factor of a number in this case 54. This is the highest number times another number which = 54. The HCF for 54 is 18.
