The shape of quadrilateral ABCD changes as the moving platform swings around, but its side lengths do not change. Both pairs of opposite sides are congruent, so ABCD is a parallelogram by the Parallelogram Opposite Sides Converse. By the definition of a parallelogram, — AB — DC .
Answer:
question 1 , area= 42.02 sq meter, circumference=22.98 meter
question 2, area=481.609sq meter, lenght of BC=263.3472 meter
for convience i converted yards to meter.
Step-by-step explanation:
in first question to find area of circle by multiplying value of pi (3.14) and square of radius of circle and to find circumference just multiply 2 with value of pi(3.14) and radius of circle.
in the second question to find area of sector use formula 1/2 r^2 x72 and to find lenght of arc bc use formula length= radius x 72
Answer:
5x - 8 = 10
Step-by-step explanation:
y = 2x - 4
x + 2y = 10
Substituting for y in equation 1 into equation 2 we get:_
x + 2(2x - 4)= 10
5x - 8 = 10
