Answer:
144 ft^2
Step-by-step explanation:
property of 45-45-90 triangle: side lengths are 12rt2
12rt2*12rt2/2=144
A. 1
b. 1
c. 1
d. 1/2
2. 1/2
3. Yes they did break it because there are 3 wholes.
I believe the answer is 142 degrees.
38 degrees and 7 are adjacent, meaning adding them up will get you 180 degrees. 180-38=142, so 7 is 142.
Number 7 and 5 are corresponding, so they are equal.
This means that 5 is 142 degrees.
(I think)
The correct answer should be 192.
3(8)^2=3x64
