Question

Q. Find the value of angle 8.

Answer 1

Answer:

<8 = <4 + <5

Step-by-step explanation:

<4 + <5  + <6 + <7 = 180  {being cointerior angles}

or, <5 + <6 = 180 - <4 - <5

<5 + <6 + <8 = 180    {Being sum of angles in a triangle}

or, 180 - <4 - <5 + <8 = 180

or, <8 = 180 - 180 + <4 + <5

or, <8 = <4 + <5
