This was on my homework 5 X-5 = 5x+7
KengaRu [80]

Answer:

No solution

Step-by-step explanation:

Original Equation:

5x - 5 = 5x + 7

Add 5 to both sides

5x = 5x + 12

So we already know that this equation is not true, making it no solution

A skier is on the top of a 350 meter tall mountain looking down at a tree. The direct path from the tree to the skier is 505 met
denpristay [2]

Answer:

43.87^{\circ}

Step-by-step explanation:

We are given that

Height of mountain=350 m

Distance  from the tree to the skier=505 m

We have to find the angle of depression from where the skier is standing to the base of the tree.

In triangle ABC

\frac{AB}{AC}=sin\theta

By using the formula

\frac{Perpendicular\;side}{Hypotenuse}=sin\theta

\frac{350}{505}=sin\theta

sin^{-1}(\frac{350}{505})=\theta

\theta=43.87^{\circ}

Hence, the angle of depression from where the skier is standing to the base of the tree=43.87^{\circ}
