Question

Write down the size of each of these angles.

a- angle ADC b- angle DBC
c- reflex angle AEB d- BCD

Answer 1

Answer:

Angle ADC = 70°

Angle DBC = 50°

Reflex angle AEB = 260°

Step-by-step explanation:

Answer 2

Answer:

a) angle ADC = 40⁰+30⁰ = 70⁰

b) angle DBC = 50⁰

c) reflex angle AEB = 360⁰-(80⁰+100⁰+80⁰)

= 360-80-100-80

= 360-260

= 100⁰

d) BCD = 50⁰+50⁰ = 100⁰
