Question

Exterior angle of a triangle is 70. Measure of its adjacent interior angle is -----

Answer 1

Answer:

110 is the angle

Step-by-step explanation:

as we see that adjacent of other angle can come 180-70 =110

Answer 2

Given:

An exterior angle of a triangle is 70

To Find:

The measure of its adjacent interior angle is

Solution:

When two adjacent angles are on a straight line then the sum of their angles is always equal to 180 degrees. It is also referred to as supplementary angles,

And when two adjacent angles are on a right angle then the sum of their angles is always equal to 90 degrees. It is also referred to as complementary angles.

Similarly, if an exterior angle of a triangle is given as 70 degrees then its adjacent interior angle can be found by using the property of supplementary angles, that goes as,

$\theta+70=180\\\theta=110^{\circ}$

Hence, the adjacent interior angle is equal to 110 degrees.
