Answer:
7.8cm
Step-by-step explanation
You first want to find what L's degree is so you do 180=139-36
L is equal to 5 degrees.
You set up the fraction L/sin5=59degrees/sin139
Cross multiply so you get Lsin139=59sin5
To get L by itself you divide by sin 139 so, L=59sin5 divided by sin 39 which is 7.83 and then you simplify it to the nearest 10th so its 7.8.
