Step by step solution

01

Step 1. Given information 

02

Step 2. Calculation 

We know,

A+B+C=180掳

50掳+B+85掳=180掳

B=45掳

Now use Law of Sines -

role="math" localid="1646914513272" sinAa=sinBb and role="math" localid="1646914524115" sinBb=sinCc

sin50掳a=sin45掳3 sin45掳3=sin85掳c

role="math" localid="1646914685507" 3sin50掳sin45掳=a c=3sin85掳sin45掳

3.3鈮�a c鈮�4.2
