Q) Find angle ABC.
​

Answer 1

Answer:

∠ABC = 155°

Step-by-step explanation:

∠RCD+∠DCS = 180 (Linear Pair)

∠RCD+60 = 180

∠RCD = 180-60

∠RCD = 120°

∠BCD = ∠RCB+∠RCD

∠BCD = 35+120

∠BCD = 155°

∠ABC = ∠BCD (Alternate Interior Angle)

∠ABC = 155°

Answer 2

Answer:

∆abc= 155

Step-by-step explanation:

It is given that: a = (22 × 33 × 54 ) and b = (23 × 32 × 5) ∴HCF (a,b) = Product of smallest power of each common prime factor in the numbers. = 22 × 32 × 5 =
