Answer: the compliment is 19° (90-71=19). the supplement is 109° (180-71=109)
Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
Answer:
the 1st option
Step-by-step explanation:
The expression should be $20.00-($0.40p)=change recieved
You can divide other shapes into triangles. Then you use what you know about the similar or congruent angles/sides (depending on your question) to determine congruency/similarity between other shapes.
