Question

an exterior angle of a triangle is of measure 70,°and one of its interior opposite angles is of measure25° find the measure of the other interior opposite angle​

Answer 1

Answer:

The answer is $45^\circ$

Step-by-step explanation:

We know that, sum of two interior angles of a triangle is equal to the third exterior angle .

Thus

One interior angle + Other interior angle $=$ third exterior angle

$\Rightarrow 25^\circ+$ Other interior angle $=70^\circ$

$\therefore$ Other interior angle $=70^\circ -25^\circ =45^\circ$

Answer 2

Answer:

45°

Step-by-step explanation:

one of the exterior angle is 70°

so it's interior angle is 110°

another interior angle is given as 25°

So the value of the remaining interior angle is 180-(25+110)

=180-135 =45°
