47 I A Find The Values Of Angles 1 2 3 And 4 Show Your Steps Or Explain Your Reasoning For Each class=

Sagot :

Angle 1 is 43 degrees
Angle 2 is 133 degrees
Angle 3 is 90 degrees
Angle 4 is 137 degrees

Angle 1 is 43 degrees because all angles inside a triangle add up to 180 degrees, so 90+47 is 137, then 180-137 is 43 degrees

Angle 2 is 133 degrees because you have to add all other angles inside a triangles except for the interior angle that is closest to the angle 2. 43 + 90 is 133

Angle 3 is 90 degrees because the right angle square is beside it, and it is a straight line. Or add other interior angles up, 47 + 43 = 90.

Angle 4 is 137 degrees because you have to add up all other interior angles other than the one that is closest to angle 4. 47 + 90 is 137.
