Question

The exterior angle of a triangle is 110degree. If one of the interior opposite angles is 55degree,what is the measure of the other? step by step​

Answer 1

Answer:

55

Step-by-step explanation:

110 = 55 + x

x = 110 -55

x = 55

Answer 2

measure of the other angle is 55°

Correct Question:-

The exterior angle of a triangle is 110degree. If one of the interior opposite angles is 55degree,what is the measure of the other

Explanation:-

we know that,

the sum of two interior angle is equal to the one exterior angle

Given:

one interior angle = 55°

one exterior angle = 110°

Approach:

i.e,

if A and B are two interior angle then their sum will be one exterior angle

Formula:

A+B(interior angles) = C(exterior angle)

Solution:

putting the value above

let,the other angle be x;

55+ x = 110

=>x=110-55

=>x=55°

Hence, the measure of other interior angle is 55°
