Ответ:
False
Step-by-step explanation:
We are given that
Opposite angles of a quadrilateral in a circumscribed circle are always complementary.
We have to find that this statement is true or not.
We know that
When a quadrilateral in a circumscribed circle is called cyclic quadrilateral.
We know that
Sum of opposite angles of cyclic quadrilateral is always 180 degrees.
When sum of two angle is equal to 180 degrees then , the angles are called supplementary.
Hence, the sum of opposite angles of cyclic quadrilateral is always supplementary.
Therefore, the given statement is false.
Ответ:
first blank is 4/25.
second blank on the top row is 16:100=4:25.
First blank on the second row is 13/50.
The second blank on the second row is 26:100=13:50.
The first blank on the third row is 33:50.
The first blank on the fourth row is 4/7.
The second blank on the fourth row is 57%.
The third blank is 0.57.
Step-by-step explanation:
16/100 simplified is 4/25. 16÷4=4 100÷4=25
ratios are also fractions.
26/100 simplified is 13/50. 26÷2=13 100÷2=50
66/100 simplfied is 33/50. 66÷2=33 100÷2=50
4÷7(rounded down)=0.57
