Answer:
17
Step-by-step explanation:
21.1cm
From sine rule which can be expressed as
b/ sinB = c/sin C
B = 57°,
b = 26 cm.
FROM THE COMPLETE QUESTION,
C=43°
Then we can substitute this
26/sin(57) = c/sin(43)
If we cross multiply and make "c" subject of the formula
c=[26 × sin(43)]/ sin57
c= 21.1 cm
21a+77b
7x3=21
7x11=77
answer :
3/4
it just is.
