Complementary angles add up to 90 degrees. Congruent angles are equal to one another (have the same degrees) Supplementary angles add up to 180 degrees.
124 + 56 = 180
The angles are supplementary
It is the first choice. 3 times 5/2 is 15/2 which equals 7.5 and 12 times 5/2 is 60/2 which equals 30. 7.5 times 30.
A :Larger because 1.5 is less than 1 .
B:Smaller because 1.5 is less than 1 .
c: Larger because 1.5 is greater than 1.
D:Smaller because is greater than 1 Time left for this assessment:
Answer:
Step-by-step explanation:
This is a circle with radius 2 and z = y
All points on or within the circle x2 + y2 +4 and in the plane z = y
Answer:
<em>x+y=4</em>
Step-by-step explanation:
hello :
note : by identity you have x²-y² = (x-y)(x+y)
in this exercice : 2x²-2y² = 2(x²-y²) = 2 (x-y)(x+y)
means : 2 (x-y)(x+y) = 40
but x-y = 5
so : 2(5)(x+y) =40
x+y=40/10
<em>x+y=4</em>
