Answer 1

e=15.8

Explanation:

Well we use the law of cosines

e^2=11^2+6^2-2(11)(6)cos(134)

`e^(2) =121+36-132cos134\\e^2=157-132cos143\\e^2=248.694....\\e=15.8`

Answer 2

15.8

Explanation:

Using Cosine rule

a² = b²+c²-2bcCos A

a = e

b = 11

c = 6

A = 134°

e² = 11²+6²-2•11•6 × Cos 134

" = 121+36 -132× -0.69466

" = 157 + 91.69512

" = 248.69512

e² = 248.6951

e = (248.6951)½

e = 15.7701

nearest tenth = 15.8
