Answer:
is the answer.
Step-by-step explanation:
In the given triangle YWZ
WZ² = YW² + YZ²
c² = 4² + 3² = 16 + 9 = 25
c = 5
In the ΔXYW
b² = 4² + a²-----(1)
In the right angle triangle WXZ
(a + 3)² = b² + c²
a² + 9 + 6a = b²+ c²
By putting value of b² from equation 1.
a² + 9 + 6a = 16 + a² + 25
6a + 9 = 41
6a = 41 - 9
6a = 32
a = 32/6 = 16/3
So is the answer.
The <BAC angle isn't a perfect right angle because the image was a photo

Answer: correct choice is A
Answer:
The height of the roof is 534.8 feet.
Step-by-step explanation:
Let h be the height of the roof.
We know the formula
Since, the stone is dropped from the edge of the roof hence, the initial velocity should be zero. Thus, u = 0
Now, we have
v = -185 feet per second
g = 32 feet per square second
On substituting these values, we get
The height of the roof is 534.8 feet.
