Answer:

A = 58 degrees

b = 51.9

c = 48.5

Step-by-step explanation:

To find A we simply just need to remember that all triangles add up to 180 degrees and we are already given two angles of the triangle so....

57 + 65=122

122+58=180

A=58

To find sides b and c we use the law of sines since we now know the angle of each side.

a=48

b=48\times\frac{sin65}{sin57} =51.87

51.87

7>5

51.9

b=51.9

c=48\times\frac{sin58}{sin57} =48.54

48.54

4

c=48.5

Hope this helps.
