Question

A linear pair of angles is in the ratio $9\ :\ 11$ . The measure of the smaller angle in degrees is $\degree$ .

Answer 1

Answer:

dont know sorry

Answer 2

Answer:

81

Step-by-step explanation:

Let,

The first angle be 9x.

The second angle be 11x.

First, we need to find the value of x.

* It is a linear pair.

We know that,

Sum of angles of the linear pair is 180°.

First angle + Second angle = 180°

Now,

9x + 11x = 180

= 20x = 180

x = $\frac{180}{20}$ = 9

ANGLES -:

1. 9x = 9*9 = 81°

2. 11x = 11*9 = 99°

SMALLER ANGLE = 81°
