Answer:

(6, -8)

Step-by-step explanation:

Solve this system by substitution: substitute (1/3)x - 10 for y in the second equation, obtaining:

2x + (1/3)x - 10 = 4, or (after multiplying both sides by 3):

6x + x = 42, or 7x = 42.

Then x = 6. Substituting this into the first equation, we get:

y = (1/3)(6) - 10 = -8

The solution is (6, -8)

A zip line takes passengers on a 200 m ride from high up in the trees to a ground level platform. If the

attashe74 [19]

The zip line forms a right triangle with the tree, when elevated

The height of the tree is 35 meters

<h3>How to calculate the height of the tree</h3>

Represent the height of the tree with h.

So, the height h is calculated using the following sine function

$\sin(10) = \frac{h}{200}$

Make h the subject

h = 200 * sin(10)

Evaluate the product

h = 35 meters

Hence, the height of the tree is 35 meters
