In a triangle, an exterior angle at a vertex is `95^0` and its one of the interior opposite angle is `55^0` , then the measure of the other interior angle is `55^0` (b) `85^0` (c) `40^0` (d) `90^0`

Text Solution

Verified by Experts

We know that, In a triangle, an exterior angle so formed is equal to the sum of the two interior opposite angles.
Let , the measure of the other interior angle is `x`.
`x + 55^@ = 95^@
x = 95^@ – 55^@
x = 40^@`
