Question

In the figure given alongside, find:
(i) angle ACD
(ii) angle AED​

Answer 1

Step-by-step explanation:

1. let angle ACB= x

• 25+45+x=180
• x=180-70
• x=110
• so angle ACB=110

2.let angle ACD= x

then x+ angle ACB = 180(angles on straight line)

x=180-110

x=70

3. let the downside angle of e be angle F

• then let angle F=x
• 40+70+x=180

x=180-110

x=70

then angle E = 180-70= 110

so angle AED=110

Answer 2

Answer:  ACD:- 110Degree and AED:-110degree

Step-by-step explanation:

let angle ACB= x

25+45+x=180

x=180-70

x=110

so angle ACB=110

2.let angle ACD= x

then x+ angle ACB = 180(angles on straight line)

x=180-110

x=70

3. let the downside angle of e be angle F

then let angle F=x

40+70+x=180

x=180-110

x=70

then angle E = 180-70= 110

so angle AED=110
