Question

Let B=,60° and C=50°Find A,L,z,yand x​

Answer 1

Line l is parallel toBC

angle C = x =50° (alternate angles)

Angle B = z =60° (alternate angles)

Angles x + y + z = 180°

(Linear pair)

50 + 60 + z = 180

z = 180-110

angke z = 70°

Answer 2

Answer:

Angle X = 50°

Angle y = 70°

Angle z = 60°

Step-by-step explanation:

Since, BCllL, ( BC is parallel to l)

z=60° (alternate interior angles)

x=50° (alternate interior angles)

Now, in triangle ABC,

angle B+angle C+angle y = 180° (angle sum property of triangle)

60°+50°+y=180°

110°+y=180°

y=180°-110°

y=70°
