Answer:
The space needle is 62.95 m tall.
Step-by-step explanation:
Given that,
The height of the shadow, h = 67 m
The angle of elevation from the tip of the shadow to the top of the Space Needle is 70°.
We need to find the height of the space needle.
The shadow of space needle is hypotenuse of right angled triangle. Let the height of the space needle is x m. Using trigonometry,
![\sin\theta=\dfrac{x}{h}\\\\x=h\times \sin\theta\\\\x=67\times \sin(70)\\\\x=62.95\ m](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D%5Cdfrac%7Bx%7D%7Bh%7D%5C%5C%5C%5Cx%3Dh%5Ctimes%20%5Csin%5Ctheta%5C%5C%5C%5Cx%3D67%5Ctimes%20%5Csin%2870%29%5C%5C%5C%5Cx%3D62.95%5C%20m)
So, the space needle is 62.95 m tall.
Answer:
x = 1/2
Step-by-step explanation:
4x - 3 + 5 = 2x + 7 - 8x
4x + 2 = -6x + 7
10x + 2 = 7
10x = 5
x = 5/10
x = 1/2
6 and 7
the square root of 43 is 6.557
