Question

B = 57°, b = 26 cm. Find c in cm. Round to 2 decimal places.​

Answer 1

17

Explanation:

Answer:

21.1cm

Explanation:

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
