he divided by 2 instead of taking the square root so the actual answer should be 26 and for the second the 20 is across from the 90 so its suppose to be c
the answer should be 16
Answer:
x = 15
y = 7.5
Step-by-step explanation:
✔️Diagonals of a parallelogram bisect each other at 90°.
Therefore,
2x° + 60° + 90° = 180° (sum of triangle)
Solve for x
2x + 150 = 180
2x = 180 - 150
2x = 30
2x/2 = 30/2
x = 15
✔️2x = 4y (alternate angles/corresponding angles)
Plug in the value of x
2(15) = 4y
30 = 4y
30/4 = y
7.5 = y
y = 7.5
204 - 120 = 84
84/120 x 100 = 70%
answer: 70% increase
1ft 9 in= 21 inches.
6ft=72 inches.
72inches - 21inches = 51 inches.
The hole needs to be 51 inches deeper
