Answer:
x = 28
y = 21
The perimeter is of 224 cm.
Step-by-step explanation:
Finding x:
We look at the top, and the bottom of the figure.
The top measures 42 cm.
The bottom measures x.
Looking on the base of y, we can see that the top can be divided into a part which is x(same as the bottom), and another of 14, measuring 42. So
x + 14 = 42
x = 42 - 14
x = 28
Finding y:
Now we apply the same logic to find y.
We look at the left side, and the right side.
They should be equal.
The right side measures 70.
The left measures 49 + y. So
49 + y = 70
y = 70 - 49
y = 21.
Finding the perimeter:
It is the sum of all edges.
P = 42 + 70 + x + 49 + 14 + y
Since x = 28, y = 21
P = 42 + 70 + 28 + 49 + 14 + 21
P = 224
The perimeter is of 224 cm.

5 x 60/6 = 50
50 x 960 = 48,000
Answer is: -->> 48,000
(4,-1) is the correct answer.
Hope this helps:)
Answer and Explanation:
Using trig ratios, we can express the given values of sin u and tan v as shown below
![\begin{gathered} \sin u=\frac{opposite\text{ of angle u}}{\text{hypotenuse}}=\frac{2}{5} \\ \tan v=\frac{opposite\text{ of angle v}}{\text{hypotenuse}}=\sqrt[]{21} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csin%20u%3D%5Cfrac%7Bopposite%5Ctext%7B%20of%20angle%20u%7D%7D%7B%5Ctext%7Bhypotenuse%7D%7D%3D%5Cfrac%7B2%7D%7B5%7D%20%5C%5C%20%5Ctan%20v%3D%5Cfrac%7Bopposite%5Ctext%7B%20of%20angle%20v%7D%7D%7B%5Ctext%7Bhypotenuse%7D%7D%3D%5Csqrt%5B%5D%7B21%7D%20%5Cend%7Bgathered%7D)
So we can go ahead and label the sides of the triangle as shown below;
We can find the value of u as shown below;
We can find v as shown below;
Answer:
63 cm^2.
Step-by-step explanation:
Total Area = area rectangle + area of triangle on right + area of triangle at the top.
= 6 * 8 + 1/2 * 1 * 6 + 1/2 * 8 * 3
= 48 + 3 + 12
= 63 cm^2.
