Answer:
A. x = 5 (Equation below)
B. AC = 9 | BD = 9
Step-by-step explanation:
A. Since we know the diagonals of an isosceles trapezoid are congruent, we know that the two bottom parts of the diagonal BD (2x - 8 and x - 4) are congruent to the diagonal AC (x + 2) . This means you can just equal them together and get the value of x:
2x - 8 + x - 4 = x + 2
3x - 12 = x + 2
3x = x + 14
2x = 14
x = 7
B. Just plug in 5 for x:
AC = x + 2 = 7 + 2 = 9
BD = 2x - 8 + x -4 = 3x - 12 = 21 - 12 = 9
Answer:
18
Step-by-step explanation:
18 over 1 is still 18. It shouldn't be a mixed number
Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:
The sum of all angles in a quadrilateral = 360°.
Therefore, 
Solve for x
The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
Answer:
The length of each side is 4 m
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
64 = s^3
Take the cube root of each side
64 ^ (1/3) = s^3 ^ (1/3)
4 = s
The length of each side is 4 m
