Workers in an office of 40 staff were asked their favourite take away. the results are summarised in the table. PIZZA - frequency =3 angle = a
CURRY - frequency=12 angle =b
FISH AND CHIPS- frequency =7 angle =c
KABAB-frequency =3 angle = d
OTHER-frequency=15 angle = e

Pizza: 27°

Curry: 108°

Fish and Chips: 63°

Kabab: 27°

Other: 135°

Step-by-step explanation:

Frequency 40 = 360°

Pizza (3) = * 360° = 27°

Curry (12) = * 360° = 108°

Fish and Chips (7) = * 360° = 63°

Kabab (3) = * 360° = 27°

Other (15) = * 360° = 135°

27 + 108 + 63 + 27 + 135 = 360

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

b

step-by-step explanation:
