Short Answer

Expert verified

The required triangle is

A=70.73掳B=70.73掳C=38.54掳

Step by step solution

01

Given information

a=3,b=3,c=2

To find the angles A,B,C

02

Calculation

ForA:cosA=b2+c2-a22bc=32+22-322脳3脳2=0.33A=cos-10.33=70.73掳ForB:cosB=a2+c2-b22ac=32+22-322脳3脳2=0.33B=cos-10.33=70.73掳

Since we know A and B

C=180掳-A-B=180掳-70.73-70.73=38.54掳
