Question

AB//CD angel BDC=40 and angle BAD=75
FIND X; Y;Z

Answer 1

Here, CDA= 40= x ( alternate angle)
Now, in triangle DAB x= 40 angle A = 75 .
sum of a triangle is 180, so
y+75+40=180
y=180-115=65
now in other triangle angle CBD = 65-5 = 60
same method , propertry of triangle
so,
40 +60+z=180
z=180-100=80
