Answer:4120
Step-by-step explanation:
I think the awnser is 8 I'm sorry if not, but It's because there are 8 outside sides and interior angle doesn't count the insides
Answer:
a = sqrt(7)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2 +3^2 = 4^2
a^2 +9 = 16
a^2 = 16-9
a^2 = 7
Taking the square root
a = sqrt(7)
Answer: 335ft
Step-by-step explanation:
The tangent of the angle of elevation is the ratio of the dam height h to the horizontal distance downriver of the observer. This gives us two equations for the height:
h= atan(1.1) = (155+a) tan(0.8)
⟹a= h/tan(1.3), 155+a= h/tan(0.8).
Subtracting the first equation from the second,
155=(155+a)−a =h/tan(0.8)−h/tan(1.1)
=h(1/tan(0.8)−1/tan(1.1)).
Solving for h,
h=155 ft (1tan(0.8)−1tan(1.1))−1
155(0.9713 - 0.5090)^-1
155(2.1631) ≈335 ft .
