X=4 and y=6
For this, you should use simultaneous equations
Answer:

Step-by-step explanation:
Using the general equation
, we already know that
and
, but we need to find
from the period:

Hence, the cosine function is 
Perimeter = 2l + 2w
Divide 184 by 4
184/4 = 46
Subtract by 6
46 - 6 = 40
Add by 6
46 + 6 = 52
The length is 52, and the width is 40.
We can verify by plugging these values into the original equation.
52*2 + 40*2 = 184
Answer:
ΔDAM ≅ ΔTUM according to Side Angle Side (SAS) rule of congruency
Step-by-step explanation:
The proof of congruency of the two triangles is as follows;
Statement
Reason
Segment DM is congruent to Segment TM
Given
Segment AM is congruent to Segment UM
Given
∠DMA is congruent to ∠UMT
Given
Therefore, ΔDAM is congruent to ΔTUM
SAS rule of congruency
Where;
SAS = Side Angle Side
Therefore;
ΔDAM ≅ ΔTUM according to Side Angle Side (SAS) rule of congruency.
Answer:
I can only do mean and median
First, you have to write it in decreasing order
1, 4, 5, 6,7,8,9,9,9,11
Now, we seperate them
1, 4, 5, 6,7,8,9,9,9,11
the two middle numbers are 7 and 8 so the median is 7.5
upper quartile: 8,9,9,9,11
lower quartile: 1, 4, 5, 6, 7
To find the mean, we have to add all the numbers and divide it by the amount of numbers. There are 10 numbers and added togetehr they are 69 so divide 69 by 10 so 6.9 for the mean and 7.5 for median
