Answer:
X=12 and z=109
Step-by-step explanation:
z has the same degree measure as the Angle across from it of 109 degrees.
to solve for x we first have to subtract 109 from 180 since it’s a straight angle to get 71. then we solve for the equation 8x-25 = 71, adding 25 to both sides, 8x=96, dividing 8 by both sides, to get x=12
Answer:
14:9
Step-by-step explanation:
you cant simplify so just put : in between the numbers and boom! ur ratio is 14 to 9 or 14:9
hope this helps :D
Answer:
d = 1/18
Step-by-step explanation:
Answer:
262 square feet
Step-by-step explanation:
The lateral surface is the side surfaces, except top and bottom.
There are 3 lateral surfaces.
The 2 sides are triangles with length 20 and height 8.5
And
The back is a rectangle with length 12 and height 8.5
We sum up all the 3 surface areas, that will give us the answer.
Area of triangle is (0.5) * length * height
So,
Area of 1 triangle = 0.5 * 20 * 8.5 = 80
Area of 2 triangles = 80 * 2 = 160
Area of rectangle = length * height
so,
Area of back rectangle = 12 * 8.5 = 102
Total Lateral Surface Area = 160 + 102 = 262 square feet

Answer:
(x, y) = (10, 4)
Step-by-step explanation:
Opposite sides are the same length, so ...
ON = LM
6x -3 = 4x +17
2x = 20 . . . . . . . . add 3-4x
x = 10
__
OL = NM
x -5 = 3y -7
10 -5 + 7 = 3y . . . . . substitute x, add 7
12/3 = y = 4 . . . . . . simplify, divide by 3
The values of x and y are 10 and 4, respectively.
