In triangle ABC, angle C is a right angle....

Question

Find the measure of angle B if side b = 105 m and side c = 139 m.

Answer 1

 In triangle ABC, angle C is a right angle. Find the measure of angle B if side b = 105 m and side c = 139 m

Answer 2

174.2m 

I think the right way to write this is "Triangle ABC, angle C is a right angle. Side AC=105m and side CB=139m what is the measure of side AB" 

105x105=11025 
139x139=19321 
11025 + 19321 = 30346 
the square root of 30346 = 174.20

Answer 3

construct a triangle ABC in which side BC=5.4cm angle ABC=60 and length of perpendicular from vertex a on side BC=3 cm
