Find the length of side BY for the given triangle.
saul85 [17]

Answer:

option 3- 5 square root 2

Step-by-step explanation:

\sin 45° = \frac{BY}{OY} \\  \\  \frac{1}{ \sqrt{2} }  =  \frac{BY}{10}  \\  \\ BY =  \frac{10}{ \sqrt{2} }  \\  \\ BY =  \frac{10 \times  \sqrt{2} }{ \sqrt{2} \times  \sqrt{2}  }   \\  \\ BY =  \frac{10 \sqrt{2} }{2 }   \\  \\  \huge \red{ \boxed{BY =  5 \sqrt{2} }}

GalinKa [24]

Answer:

  B, C, E, F

Step-by-step explanation:

The following relationships apply.

  • the diagonals of a parallelogram bisect each other
  • the diagonals of a rectangle are congruent
  • the diagonals of a rhombus meet at right angles
  • a rectangle is a parallelogram
  • a parallelogram with congruent adjacent sides is a rhombus

__

CEDF has diagonals that bisect each other, and it has congruent adjacent sides. It is a parallelogram and a rhombus, but not a rectangle. (B and C are true.)

ABCD has congruent diagonals that bisect each other. It is a parallelogram and a rectangle, but not a rhombus. (There is no indication adjacent sides are congruent, or that the diagonals meet at right angles.) (E and F are true.)

The true statements are B, C, E, F.

How would you round the number 32 to the nearest 100
saw5 [17]

Answer:

Remember, we did not necessarily round up or down, but to the hundred that is nearest to 32. When rounding to the nearest hundred, like we did with 32 above, we use the following rules: A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

What is the area of this polygon? Enter your answer in the box. units²
Gemiola [76]

Answer:

The area of the polygon is 39\:units^2

Step-by-step explanation:

Sketch the polygon to obtain the figure in the attachment.

The polygon can then be divided into a rectangle and a triangle.

The area of the polygon

=|VE|\times |DE|+\frac{1}{2}\times |DE|\times |AM|

We use the absolute value method to find the lengths

=|3--2|\times |3--3|+\frac{1}{2}\times|3--3|\times |5-2|

=5\times 6+\frac{1}{2}\times 6\times 2

=30+9

=39\:units^2
