Answer:
15√2
Step-by-step explanation:
Tan 45° = 1, and tan = (opposite side)/(adjacent side)
We can set up an equation as follows...
tan 45° = x/(15√2)
Solve it...
1 = x/(15√2)
multiply both sides by 15√2 to isolate 'x'
15√2(1) = (15√2)x/(15√2)
15√2 = x ( the 15√2 in the numerator and denominator cancel out)
Answer:
The correct option is:
Building B; it is around 16.35 feet taller than building A.
Step-by-step explanation:
Consult the diagram below where the first figure represent building A and second figure represents building B
For building A:
tan θ = Perpendicular / Base
tan 73° = Height of building A / 30
Height of building A = tan73 · 30
Height of building A = 98.13 ft
For building B:
tan θ = Perpendicular / Base
tan 73° = Height of building B / 35
Height of building A = tan73 · 35
Height of building A = 114.48 ft
Building B is taller
Difference in height = height of building B - height of building A
Difference in height = 114.48 - 98.13 = 116.35 feet
The smallest number of acute angles a triangle can have is 2
Answer:
530.66
Step-by-step explanation:
The way we find the area of the circle we use the radius of the circle for this one it's 13cm squared * pi or 3.14
For this circle we do 3.14 * 13^2
First we have to square 13: 13^2 = 169
Then we multiply 169 by 3.14: 3.14 * 169 = 530.66
Then we do to the nearest hundredth which is the same as the previous answer: 530.66
