In the adjoining figure, ∠a = (120 - x)o and ∠b = 5xo, the measures of ∠a and ∠b.
125o, 55o
52o, 65o
75o, 75o
100o ,100o
The corresponding angles are equal
(120 - x)o = 5xo 6x = 120o
x = 20o
a = 120o- 20o= 100o, b = 5 x 20o = 100o
In the adjoining figure, if PQ || RS, ∠PAB = 45o and ∠ACS = 135o, the value of p and q
In the given figure, a || b and c || d. If ∠1=75∘, what is the measure of ∠3?
