I really need help please!
pashok25 [27]

As we know that angle of semi circle is 180°.

Here,

FLG = 40°

GLH = ?

HLJ = 60°

FLG + GLH + HLG = 180°

40° + GLH + 60° = 180°

GLH + 100° = 180°

GLH = 180° - 100°

GLH = 80°

Now,

FLH = 40° + 80° = 120°

\sf \: Length \:  of  \: an \:  arc  \: of \:  GHF =   \dfrac{ \theta}{360}  \times 2 \pi \: r

=  \dfrac {120}{360}  \times 2 \times  \dfrac{22}{7}  \times r

=  \frac{1}{3}  \times  \frac{44}{7}  \times r

=  \frac{44}{21}  \times r

= 2.09r

If 12 and 20 each divide K without a remainder, what is the value of K?
Juli2301 [7.4K]

Factors of 12 : 1, 2, 3, 4, 6, 12

Factors of 20: 1, 2, 4, 5, 10, 20

In both lists of factors, 4 is in common. Therefore, the value of K is 4 because it can divide into both 12 and 20 without a remainder. 2 is also another possible value of K.
