Question

Find the length of side e to the nearest tenth in the triangle below.

Answer 1

Answer:12.1

Step-by-step explanation:

Angle D=180-(82+52)

Angle D=180-134

Angle D=46

Using sine rule

e/sinE=d/sinD

e/sin52=11/sin46

e/0.7880=11/0.7193

e/0.7880=15.29

Cross multiply

e=15.29 x 0.7880

e=12.05

e=12.1 approximately
