Answer:
389 feets apart
Step-by-step explanation:
Given that:
Building A
Height = 400feets
Angle of elevation = 70°
Building B:
Height = 300 feets
Angle of elevation = 52°
Distance from the foot of building A to where Jonny is standing = x (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 70 = 400/ x
2.7474774x = 400
x = 145.58809 feets
Distance from the foot of building B to where Jonny is standing = y (see attached picture)
Using trigonometry :
Tanθ = opposite / Adjacent
Tan 52 = 300/ y
1.2799416y = 300
y = 145.59
y = 234.38568 feets
x + y = distance between the two buildings
(145.58809 + 234.38568) feets
= 379.97377
= 380 feets apart
Do 15.5×12
then you will know how much ribbon you need. Hope that helps!
The right answer is not among those offered. The domain is
.. {-9, -6, 4, 7}
___
The 4th selection {4, 7} is the best of those offered, but it is not correct.
Yes because they all have multiples of 3.
Also 4*3=12 and 3*3=9 so 4/3 is equal to 12/9.
Answer:
1254.24
Step-by-step explanation:
Total area = sum of area of half circles and square
Area of square = 576
Area of half circles = 216π
So total area 576 + 216π
It says use 3.14 for π
So we get total area = 576 + 216(3.14)
==> multiply 216 and 3.14
total area = 576 + 678.24
==> add 576 and 678.24
total area = 1254.24
