Answer:
The measure of the angles a, b, c, d are 65°,115°,65°,115°
Step-by-step explanation:
here,
l is parallel to m and p is parallel to q.
then
\angle a = 65^\circ∠a=65
∘
(vertical opposite angle )
since , l ║ m and q is the transversal line then
\angle a+\angle d = 180^\circ∠a+∠d=180
∘
(angle on the same side of the transversal )
65 +d = 180°
d = 180-65
d = 115°
now p ║q and m is the transversal line
c +d = 180°(angle on the same side of the transversal )
c + 115° = 180°
c = 180-115
c = 65°
similarly
b +c = 180°
b + 65°= 180
b = 180-65 = 115°
hence ,
The measure of the angles a, b, c, d are 65°,115°,65°,115°
Tp is a tangent to the circle with centre o.if angle toq=120degree,find the diameter if the circle when ot=10cm
