Question

Howard is designing a chair swing ride. The swing ropes are 55 meters long, and in full swing they tilt in an angle of 29? . Howard wants the chairs to be 2.75 meters above the ground in full swing. How tall should the pole of the swing ride be?

Answer 1

if this is from Khan, and it's 5 not 55,

the answer is 7.12

Explanation:

5 x cos29 = 4.373098536

4.373098536 + 2.75

7.123098536

rounded = 7.12

Answer 2

Answer: 50.85 meters

Step-by-step explanation:

cos 29 = $\frac{55}{h}$

55 cos 29 = h

48.10 = h

Pole  = h + 2.75

        = 48.10 + 2.75

         = 50.85
