Question

two angles forming linear pair in ratio 11 is to 7 find the angles

Answer 1

We know that linear pairsmake a sum of 180°
Method one

Sum of ratios = 11 + 7 = 18
value of 11 =
$\frac{11}{18} \times 180 = 110$
value of 7 =
$\frac{7}{18} \times 180 = 70$

Method 2
Assume angles to be 11x and 7x
so
11x + 7x = 180
18x = 180
x = 180/18
x = 10

11x = 11 × 10 = 110
7x = 7 × 10 = 70



Hope it helps dear friend ☺️✌️
