Question

in triangle abc of the adjoining figure de || bc . if angle b = 30 and a = 40 . find the value of x , y , z​

Answer 1

Answer:

y = 90 degree

z = is also 90 degree because both triangle are similar or right angle triangle.

x = 30 degree because both triangle are similar

Step-by-step explanation:

angle ABC=angle ADE

30=30

angle x=30

angle y =angle z

x+z+40=180

30+z+40=180

70+z=180

z=180-70

z=110

angle z=angle y=110

angle x=30

angle y=110

angle z=110
