DBH make a triangle.
The three inside angles of a triangle need to equal 180
H = 180 - B - D
H = 180 - 39 - 36 = 105
H and X make a straight line that equals 180 degrees
X = 180 - H
X = 180 - 105 = 75 degrees.
Answer:
133 ft
Step-by-step explanation:
Given in the question,
length of the rectangle = 31 ft
width of the rectangle= 20 ft
diameter of semicircle = 20 ft
radius of semicircle = 20/2 ft = 10 ft
Formula to use:
<h3>perimeter of rectangle + perimeter of semicircle</h3>
perimeter of rectangle = 2(l+w)
perimeter of semicircle = 1/2(2πr)
Plug values in the formula above
2(31 + 20) + 3.14(10)
133.4 ft
≈ 133 ft
Answer:
48 divided by 3 = 16
Step-by-step explanation:
If you divided 54 apples into 6 groups, 9 apples are in each group.
To determine x intercept get y=0 then substitute in equations: y=6x-11
0=6x-11 then x= 11/6
To determine y intercept get x=0 then substitute in equations: y=6x-11
y=6(0)-11 then y=-11
