Question

two angles of triangle are 45degree and55degree find the measure of third angle​

Answer 1

Answer:

Angle 1 =45°

Angle 2= 55°

Angle 3= ?

As we know that by using angle sum property of a triangle the sum of all the three interiors angles of a triangle is 180°.

So, Angle 3=180°-(angle 1 +angle 2)

=> 180°-(45° + 55°)

=>180°-100°

=>80°

Answer 2

Answer:

80°

Step-by-step explanation:

<a+<b+<c=180°

45°+55°+<c=180°

100+<c=180°

<c=180-100

<c =80°
