1. Find the value of the unknown exterior angle x in the
following diagram angle 1 65° angle 2 45°​

Answer 1

Answer:

Diagram is not there still

<1 + <2 + <x= 180°

65° + 45° + <x =180°

<X + 110° = 180°

<X = 180°-110°

<X = 70°

Answer 2

Step-by-step explanation:

let x be the unknown exterior angle

now, by using angle sum property, we have:

1°+ 2°+ x°=180°

65°+45°+x=180°

110°+x=180°

x=180°-110°=70°

therefore, the required angle =70°
