Yes, DEF and RPQ are congruent.
Answer: x=14
Step-by-step explanation:
Add 5 to both sides to get the x alone and get your answer.
Is the answer four hundred twelve
Answer:
Identity element property
Step-by-step explanation:
The property that justifies the step 3 is the identity element property.
Mathematically, the identity element is that number such that performing an arithmetic operation such as addition or multiplication with the number gives back the number we started with
For addition, the identity element is 0
while for multiplication, the identity element is 1
what do we need to know:
the radius of the semi circles;
the area of:
purple region = area of a circle = pi * r^2;
green region = base * height;
what we know:
the base, 28m;
what the sum of the two diameters is, 28;
the length of a single diameter, 14;
what we can assume:
the two semi-circles are equal, as otherwise i cannot see a way to answer this;
the radius of the two semi-circles, 7m as the two diameters = 28, & d/2 = r
what does that mean:
the height is 17m
green region area = 476 m^2
purple region area is = 153.96 m^2
