Question

ABllCD and then find angle ADE
​

Answer 1

Answer:

60⁰

Step by step explanation:

Angle ADC = 40⁰

Then angle A = 40⁰ ( because interior opposite angles are equal)

Angle FAB = 80⁰

Then angle ABD = 80⁰ ( because interior opposite angles are equal)

The sum of all the angles of a triangle = 180⁰

So, ∆ADB = 180⁰

So, angle ADB = 180⁰-(80⁰+40⁰)

= 180⁰-120⁰

= 60⁰
