Im not sure but i think it is 11
Answer:
1675 ft
Step-by-step explanation:
For us to calculate how close the windmill is to the fire, if we imagine it as a triangle, the distance from watch tower to the fire will be:
tan θ= opposite/adjacent
opposite=140 ft
adjacent = x
θ=3°
Thus;
tan 3 = 140/x
x=140/tan 3
x = 2,671.359 ft
Now, the distance from watch tower to windmill will be:
tan θ=opposite/ adjacent
θ=8°
opposite=140 ft
adjacent=y
thus
tan 8 = 140/y
y = 140/tan8
y=996.15 ft
Now, the distance between fire and wind mill will be:
x - y = 2671.359 - 996.15
x - y = 1675.209 ≈ 1675 ft
264 jumps in 4 minutes
132 jumps in 2 minutes
66 jumps in 1 minute
40+60+y=180
y=180-100
y=80
A triangle is 180° so you add all the numbers available in the trianle and minus it with 180 to see what is left from the 180 and that will be the inner angle answer
X=180-80=100
A straight line is also 180° so if u minused one side which in our case is 80 u will get the rest which is the outer angle
Answer:
4(5) -7
Step-by-step explanation:
4(5) -7
The product of 4 and 5 means that 4 and 5 are multiplied together.
"7 less than," means subtracting 7.
That means you get 4(5) - 7
