Answer:
5) Ans;
The two angle 7 and 8 —> 7x and 8x
Sum of two supplementary angle is 180°
7x +8x =180
15x =180
x= 180/15
x = 12°
7x =7(12)= 84°
8x = 8(12)= 96°
The angles; 84° , 96°
6) Ans;
The two angle 4 , 5 —> 4x and 5x
Sum of two complimentary angle is 90°
4x+5x =90
9x =90
x=90/9
x=10
4x—> 4(10) = 40°
5x —> 5(10) = 50°
The angles; 40° , 50°
7) Ans;
q= 135 ( Vertically Opposite angles)
q+p = 180
135+p=180
p=180-135
p = 45°
_______o_____o_____
a= 70° ( Alternate angles)
a+ b = 180
70 + b = 180
b =180 - 70
b = 110
So ; angle a=70° , b = 110°
