Question

12. Find:
(i) angleB (ii)angleEDC
(iii) angleADE (iv) angleAED
(v) angleDEC (vi) angle DCE
(vii) angleACB ​

Answer 1

Answer:

1) angle will be will be e 55 degree (angle sum property of triangle)

6) first you have to find the whole c angle equal to70 degree then subtract 25 degree from 70 degree equal to 45 degree so your angle DCE is 45 degree

2 )angle ADC will be 25 degree

3) your ADE will be 55 degree

4)AED will be e 70 degree because angle sum property of triangle

5) angle DEC is equal to 110 degree

7) angle ACB will be e 45 degree
