The shapes are similar and not congruent because one is 5 units wide while one is less than 5 units. They are the same exact shape but different size making them similar.
5 * 1/2 - 8 ( 3/4 * 1/2 + 1/2 )
5/2 - 8 ( 3/8 + 1/2 )
5/2 - 8 ( 7/8 )
5/2 - 56/8
-36/8 = -9/2
A is the answer
Answer:
137°
Explanation:
In any triangle, the measure of the exterior angle is equal to the summation of the measures of the other two non-adjacent angles.
In the given triangle:
Angle 1 is an exterior angle.
The measures of the non-adjacent angles are 103° and 34°
Based on the above theorem:
measure angle 1 = 103 + 34 = 137°
Hope this helps :)
