Answer:
Step-by-step explanation:
The angle of X would equal 104 degrees. The reason behind that would be because it is a vertical angle, meaning it equals the same amount vertical to itself.
To get angle Y, you would need to add 104 and 56 together (160) to find the last angle. Knowing that all triangles equal 180 degrees, you subtract 160 from 180, resulting in 20 degrees. The angle of Y equals 20 degrees.
X = 104 degrees
Y = 20 degrees
Answer:
208
Step-by-step explanation:
First term = a = 4
Common difference = d = a2 - a1 = 9 - 3 = 6
35th term = a + (35 - 1)d
4 + (35 - 1)6
4 + (34)6
4 + 204

First of all, let's remember the formula for calculating area. <em><u>Length times width equals area.</u></em> (lxw=a)
Now that we have the formula. Let's take the length (8 cm) and the width (6 cm) and add 1 cm to each of them.
Length: 8+1=9.
Width: 6+1=7.
Now, let's apply the formula for area.
9 x 7 = 63
Now that we've found the area is 63 cm, let's find the perimeter. To find the perimeter of a rectangle, we must multiply the length by 2 and the width by 2, then we add the two numbers. In this case, here's what we'll do:
9 x 2 = 18
7 x 2 = 14
18 + 14 = 32
Now we have the area and perimeter.
Final answer(s):
Area = 63 cm.
Perimeter = 32 cm.
Hope this explanation helped you out. :)
