That triangle's upside down but the usual rules hold.

We know the side opposite the 39 degree angle is 10 m and we're asked for the adjacent side. The unlabeled side is the hypotenuse.

That's tangent:

$\tan 39^\circ = \dfrac{10}{x}$

$x = \dfrac{10}{\tan 39^\circ} \approx 12.35 \textrm{ m}$

For (x - 1)(x - 7) to equal 0, either (x - 1) or (x - 7) must equal what?

Kisachek [45]

$(x - 1)(x - 7) = 0$

${x}^{2} - 8x + 7 = 0$

${x}^{2} - 8x = - 7$

$- 7x = \frac{ - 7}{x}$

$x = \frac{ - 7}{ \frac{x}{ - 7} } \implies x = x \implies x \in \mathbb{R}$

x is true for any number in real domain.

Answer: Both

Explanation: The triangles all have corresponding congruent angles. We can tell this by finding the third angle of the original problem: 96.

Then you can read each triangle by what it states. Angle A is congruent to the corresponding angles in the other triangles, which are Q and T. Angle B is congruent to the corresponding angles in the other triangles, which are R and U. Angle C is congruent to the corresponding angles in the other triangles, which are S and V.

We know heard similar since they have congruent angle measures in corresponding spots.
