Answer 1

Answer:

angle 9 +angle 1 =180 is the right answer mark me as brainliest and follow me please

Answer 2

Answer:

C) angle 4 + angle 3 - angle 1 = angle 2

Step-by-step explanation:

we know that angle on a straight line made up to 180°

》in the given diagram we can say,

》angle 3 + angle 4 = 180° ...... (1)

..........(by the above property)

similarly, we can say

》 angle 1 + angle 2 = 180° ........ (2)

equating equation 1 and 2 where

》angle 3 + angle 4 = angle 1 + angle 2 = 180°

bringing angle 1 left side

》angle 4 + angle 3 - angle 1 = angle 2
