Find The Sizes Of The Three Unknown Angles In The Image Below Give Your Answers In Degrees B С A 34 class=

Sagot :

Answer:

Step-by-step explanation:

angle d is adjacent to angle b so angle be equals to 34 degree

angle a is perpendicular to angle b so

angle b + angle a = 180

34 + a =180

so 180 - 34 =146

therefore angle a = 146

since angle c is adjacent to angle a

then angle a = 146
