Answer:
19.42 ft.
Step-by-step explanation:
The diameter of the semicircle is 6, so 3.14 x 6 = 18.84. Since it is a semicircle, we divide that by 2 to get 9.42.
The hypotenuse of the right triangles only matter for the perimeter. 5 + 5 = 10, and 9.42 + 10 = 19.42 ft.
Answer:
<h2>4 ft x 7 ft = 28 sq ft
</h2>
Step-by-step explanation:
Assuming that each section is rectangular, each area can be found with
Where 
is width and 
is length.
Notice that the area of each section is found with the product of width and length, that means the right answer must be a product.
Therefore, the right answer is the second choice.
The answer is +12 because you add on 12
Answer:
Step-by-step explanation:
1. expand.
2. Subtract 8x from both sides.
3. simplify 10x - 2 - 8x to 2x - 2.
4. Add 2 to both sides.
5. Simplify 6+2 to 8.
6. Divide both sides by 2.
7. Simplify 8/2 to 4.
8. switch sides.
Therefor, rhe answer is x=4
Answer:
- a. ∠Y, ∠W, ∠X
- d. 75°
- d. 5
Step-by-step explanation:
1. The sides, shortest to longest, are 5, 10, 12. The angles opposite are in the same order (smallest to largest). Those angles are ∠Y, ∠W, ∠X.
__
2. The triangle isosceles, so the base angles are equal. The sum of angles in a triangle is 180°, so you have ...
30° + 2x = 180°
15° + x = 90° . . . . . divide by 2
x = 75° . . . . . . . . . . subtract 15°
__
3. The midline of a triangle is half the length of the base it is parallel to, so ...
ML = 10/2 = 5
It is a <em>midline</em> because it joins the midpoints of two sides of the triangle.
