Please help!!!<br><br> What is the measure of ∠DCB?<br> Enter answer below<br> __

Tom [10]

Answer:

m<DCB = 84°

Step-by-step explanation:

ABCD is a parallelogram since it has two sets of parallel sides.

Opposite angles in a parallelogram are congruent.

Consecutive angles in a parallelogram are supplementary.

<DCB is consecutive to <D.

m<DCB + m<D = 180°

m<DCB + 96° = 180°

m<DCB = 84°

which of the following properties could be used to rewrite the expression (2/3•1/5)•5/2 as 2/3•(5/2•(5/2•1/5) sorry to ask Su ma

slamgirl [31]

The original expression is given by:
$( \frac{2}{3}*\frac{1}{5})*\frac{5}{2}$
The correct way to rewrite the expression is given by:
$\frac{2}{3}*(\frac{5}{2}*\frac{1}{5})
$
For this, we use two properties:

Associative property:
The way of grouping the factors does not change the result of the multiplication:
$\frac{2}{3}*(\frac{1}{5}*\frac{5}{2})$

Commutative property:
The order of the factors does not vary the product:
$\frac{2}{3}*(\frac{5}{2}*\frac{1}{5})$
