(ii) Find the angle which is equal to its supplement.
6. Two complementary angles are (x + 4)º and (2x – 7)º, find the value of x.
7. Two supplementary angles are in the ratio of 2 :7, find the angles.​

Answer 1

Step-by-step explanation:

5(i)45

(ii)90

6) x+4+2x-7=90

3x-3=90

3x=87

x=29

7)2x+7x=180

9x=180

x=20

angles

2(20)=40

7(20)=140
