Question

Find the measures of the exterior angle of a triangle if its remote interior angles are 60degree and 55degree

Answer 1

Answer:

115°

Step-by-step explanation:

let abc be a triangle

angle a and angle b is the remote angle of measure 60 and 55 degree respectively..

angle acd is the exterior angle..

angle acd = angle a + angle b

=60+55

=115

Answer 2

The measures of the exterior angle is 115°

Step-by-step explanation:

Consider the provided information.

Remote interior angels: Angles which do not share the outer angle with a vertex or corner of a triangle. The measure of external angle is equal to the sum of the two remote interior angles.

It is given that the measure of remote interior angles are 60 degree and 55 degree.

We need to find the exterior angle.

We can find this by adding the two remote interior angles.

$\text{The measures of the exterior angle}=60^0+55^0$

$\text{The measures of the exterior angle}=115^0$

Hence, the measures of the exterior angle is 115°
