Answer:
1. BC = 25
2. m∠EDC = 125°
3) BD = 22
4) m∠EBD = 67°
5) FC = 17
6) m∠BEC = 24°
7) CD = 16
8) m∠DBC = 58°
Step-by-step explanation:
The dimensions of parallelogram EBCD are;
EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°
1. BC = ED = 25 Opposite sides of a parallelogram are equal
2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal
m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary
m∠EDC = 180° - m∠BCD
∴ m∠EDC = 180° - 55° = 125°
m∠EDC = 125°
3) BD = BF × 2 Diagonals of a parallelogram bisect each other
∴ BD = 11 × 2 = 22
BD = 22
4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines
5) FC = EC/2 from diagonals of a parallelogram bisect each other
∴ FC = EC/2 = 34/2 = 17
FC = 17
6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines
m∠BEC = 24°
7) CD = EB = 16 Opposite sides of a parallelogram are equal
8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal
m∠DBC + m∠EBD = m∠EBC from angle addition postulate
∴ m∠DBC = m∠EBC - m∠EBD
m∠DBC = 125° - 67° = 58°
m∠DBC = 58°
Find the length of a side of a square if its area is:
0.49 square units
Answer:
Side = 0.7 units
Step-by-step explanation:
Area of a square = 0.49 sq. units
Side² = 0.49
side² = [tex]\frac{49}{100}\\\\[/tex]
[tex]side = \sqrt{\frac{49}{100}}=\sqrt{\frac{7*7}{10*10}}\\\\sides=\frac{7}{10}=0.7[/tex]

Step-by-step explanation:
Answer:
x² - 22x + 121
Step-by-step explanation:
(x-11)² is the same as (x-11)(x-11)
multiply the x in the first parentheses by x and -11 in the other parentheses and multiply the -11 in the first parentheses by x and -11 in the other parentheses and add all together

Find the measures of the numbered angles in each rhombus
Answer:
2=41 1=49 3=49
Step-by-step explanation:
Angle 2 = 41 because it is directly across the given angle.
Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.
41+41=82
180-82=98
98 / 2 = 49
Angles and 3 both equal 49
Answer:
2=41°(Alternate Interior angles)
1=41°(diagonal of rhombus bisects the interior angles)
3=49°(180-82/2)
Step-by-step explanation:
Solve the inequality for x: 1/2(2x + 4) = 3x -6
An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798

Answer:
EF = 36
Step-by-step explanation:
On a rhombus, all sides are equal because its a parallelogram so,
EF = FG
we first have to find what x equals so . . .
let's plug in the numbers
4x - 20 = 2x + 8
Now we combine like terms
we add 20 to both sides
so now it would be
4x = 2x +28
Now we subtract 2x from both sides because we want x by itself
this would equal
2x = 28
now we divide two from both sides this equals
x = 14
now we insert the numbers in the equation
4 x 14 - 20 = 36
