The answer is really simple just do 3 plus 5 which is 8 so the answer is 8x
Answer:
35 cm
Step-by-step explanation:
To find the area of the bottom portion, you would use the formula for finding out a triangle (B*H*1/2) which is:
(4+4)*5.75*1/2=<u>23</u>
Then, for the top portion, one would find the area of the triangles on the sides (with two marks going through). Since along the middle is 8cm, and along the top is 4, we can see that there is 2cm on either side, so that is the length of the base of the triangle. To solve for the top triangles, you would do almost the same thing as the last one:
2*2*1/2=2
But since there's two identical triangles on either side, we can multiply that by two, which would bring it to <u>4</u>.
That just leaves the rectangle that is left between the two triangles. To solve this, it's just B*H and luckily both of those are labeled for you already:
4*2=<u>8</u>
Now, to find the total area, all you have to do is add up the areas of the different sections:
23+4+8=35 cm
Hope this helps!
Since a pentagon can be divided into 3 triangles and each triangle has interior angles equal to 180, 3 * 80 = 540. All the interior angles of a pentagon add up to equal 540. We are given the first one of 140. That is where we will start. The angle right next to that one to the right is supplementary to the 60 degree exterior angle, so the measure of the next interior angle is 180 - 60 = 120. The angle next to that in line has an exterior angle measure of 84. So 180 - 84 = 96. Next in line is an angle with an exterior measure of 68, so 180 - 68 = 112. Adding up all the bolded angle measures gives us that the last interior angle measures 72. But we want the measure of x which is an exterior angle. 72 and x are supplementary, therefore, 180 - 72 = x. x = 108. Choice B.
Answer:
A = 36 cm^2
Step-by-step explanation:
The perimeter of a square is given by
P =4s
24 = 4s
Divide by 4
24/4 = 4s/4
6 =s
The area of a square is
A =s^2
A = 6^2
A = 36 cm^2
Answer:
-3 / 4
Step-by-step explanation:
To find the slope, identify two points on the graph that cross through grid line intersections. The points (-3,2) and (1,-1) are on the line and cross through these intersections. Count the vertical and horizontal distance between these points.
Vertical: -3
Horizontal: 4
Make a ratio as a fraction of vertical / horizontal.
-3 / 4
