What is the length of GH¯¯¯¯¯¯, to the nearest tenth of a meter? 7.3 m 13.7 m 14.1 m 19.4 m A scalene triangle G H J. The base s

nlexa [21]

By applying the law of sines.

$\frac{GH}{sin \ J} = \frac{GJ}{sin \ H}$

Given:
GJ = 10 , ∠J =45° , ∠H = 31°

∴ $\frac{GH}{sin \ 45} = \frac{10}{sin \ 31}$

∴ GH = 10 * sin 45° / sin 31° ≈ 13.7 m

What is the rule for the reflection?

antoniya [11.8K]

The figure is being reflected over the x axis (horizontal axis). Any y coordinate that is negative becomes positive, and vice versa. The x coordinate stays the same.

If we have some point (x,y) as the original point, then it would turn into (x,-y). Note how the y coordinate has a negative on it now.

So we can say $(x,y) \rightarrow (x,-y)$ which is what choice C is saying.

Choice C is the answer

Choice D is NOT the answer because the words "y axis" under the 'r' should be "x axis" instead.
