Question

Please find the unknown angles.

Answer 1

so we give name abc so now you understnqd

Answer 2

Answer:

Hence the unknown angle which we assumed as x is 110

Step-by-step explanation:

Given = <1 = 65 and < 2 = 45

We know that the sum of all the angles of a triangle is 180

<1+<2+<3=180

65+45+<3 = 180

110 + <3 = 180

<3 = 70

On observing above diagram,

Let the unknown angle be x

x+<3 = 180. {linear pair}

x + 70 = 180

x = 110

Hence the unknown angle which we assumed as x is 110
