Step-by-step explanation:
here,,
a=3,b=10,C=120°
c^2=a^2+b^2-2ab cos120°
=(3)^2 +(10)^2 _2 (3)(10)(-1/2) [cos120°=-1/2]
=9+100-(-30)
=109+30
=139
c=(139 )1/2=11.79
c=12
Answer:
120:80 I think this is the answer
Step-by-step explanation:




15+70+45=130 :)) that’s how u calculate the perimeter just add them all together.
The number of eats of corn which have been picked is; 16.9 corns.
<h3>How many eats of corn have been picked?</h3>
According to the question; 16 eats of corn are being picked foot every 18 peppers. In essence, the ratio of corns to peppers is; 16/18.
Hence, it follows that the number of corns which corresponds to 19 peppers been picked can be evaluated as follows;
16/18 = x/19
x = (19×16)/18
x = 16.9 eats of corn.
