Question

7. In the following figure, D and E are points on sides AB and AC of A ABC respectively such that DE || BC. If ZB = 30° and 2A = 40°, find x, y and z.​

Answer 1

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
