Hello there!
Let me try :)
You decided to tell someone to make a book for you. You need to tell him what shape you would like the book to have. But since you want it to be quadrilateral, you need to go there and make sure that the person is doing it correctly. So that they don't give you the book with a shape of a triangle, then you would have problem to add it on your shelf because it wouldn't look interesting.
Note: A quadrilateral is defined as a polygon (a closed shape) with 4 sides,
so any shape/object with four sides can be considered a quadrilateral.
I hope this helps!
Answer:
180°
Step-by-step explanation:
Supplementary angles are angles whose sum is 180°. If L and M are supplementary, the sum of their measures is 180°.
x=3 and y=−2
Step-by-step explanation:
Solve8x+5y=14for x:
8x+5y=14
8x+5y+−5y=14+−5y(Add -5y to both sides)
8x=−5y+14
8x8=−5y+148(Divide both sides by 8)
x=−58y+74
Step: Substitute−58y+74forxin−4x−5y=−2:
−4x−5y=−2
−4(−58y+74)−5y=−2
−52y−7=−2(Simplify both sides of the equation)
−52y−7+7=−2+7(Add 7 to both sides)
−52y=5
−52y−52=5−52(Divide both sides by (-5)/2)
y=−2
Step: Substitute−2foryinx=−58y+74:
x=−58y+74
x=−58(−2)+74
x=3(Simplify both sides of the equation)
