If it is 2/3 of length, should be 60 cm?
r and 5 both make 197
r would be a use of a number that isn't known unless you rearrange the equation
The equation would be 5r = 197 or 5 x r = 197
So you could make r the subject,
And to find it, you could divide 197 by 5
197 / 5 = r
Which then would make r = 39.4
Step-by-step explanation:
find B° = m∆-90°-50°
= 180°-90°-50°
B°=40°
find c
since cos(b) = 27/c
cos(40°) =27/c
c=27/cos(40°)
c≈35.246
fin b
since sin(b) = b/c
sin(40°)=b•c
b= sin(40°)•c
b≈22.656
Answer: A is the answer
