An isosceles triangle ABY has a base AB of length 5 cm and an angle at the primary vertex of 50°. Write down the construction progress.

Final Answer:

b =  5.9 cm

Step-by-step explanation:

c=AB=5  cm Y=50   1. AB; AB=5 cm 2. S ; S  AB; AS=BS = 2.5 cm 3. p; pAB; S  p 4; ABZ; ABZ = 90  50 = 40   5; Y; Y = BZ  p 6. Δ ABY  b=5.9=5.9 cm
