Question

find the unknown angle in the given figures.
find say as soon as possible it's urgent ​

Answer 1

Answer:

angle b = 55 d

a = 85 d

c = 40 d

Step-by-step explanation:

angle b and c are supplementary angles

:. b = 180 - 125 = 55 d

 c = 180 - 140 = 40 d

  (when we have 2 angles we can find the third, sum of angles = 180)

:. 55 + 40 + a = 180

:. a = 85

:.<a = 85 degree

<b = 55 degree

<c = 40 degree
