Answer: 18
Step-by-step explanation:
2 degrees per hour
9 hours
1hour = 2 degrees
2hours= 4 degrees
3hr= 6 degrees
4hr= 8 degrees
5hr=10 degrees
6hr= 12 degrees
7hr= 14 degrees
8hr= 16 degrees
9hr= 18 degrees
So you are basically doing 2x9 to get your answer
Answer:
Building B, it is around 16 35 feet taller than building A ( C )
Step-by-step explanation:
<u>Calculating the height of Building A </u>
Height = opposite ( ? )
∅ = 73°
base/adjacent = 30 ft
∴ Height = Tan 73° * base
= 3.2709 * 30 = 98.127 ft
<u>Calculating the height of building B </u>
∅ = 73°
base/adjacent = 35 ft
∴ height = Tan 73° * base
= 3.2709 * 35 = 114.4815
Therefore we can say Building B is Taller by approximately 16.35 feet
Answer:
x=12
Step-by-step explanation:
x+7=19
-7 -7
x=12
Answer:
Step-by-step explanation:
Let x be the adjacent side length in cm
opposite side is x + 2 cm
hypotenuse is x + 4 cm
x² + (x + 2)² = (x + 4)²
x² + (x² + 4x + 4) = (x² + 8x + 16)
x² - 4x - 12 = 0
(x - 6)(x + 2) = 0
so either
x - 6 = 0 x = 6
or
x + 2 = 0 x = -2
positive answer is x = 6 as negative length does not make sense
opposite side is 6 + 2 = 8
hypotenuse is 6 + 4 = 10
perimeter is 6 + 8 + 10 = 24 cm
