Answer:

12/5

Step-by-step explanation:

tan A = opp/adj

For angle theta, 12 is the opposite leg.

13 is the hypotenuse.

We were not given the length of the adjacent leg, but we can use the Pythagorean theorem to find it.

a^2 + b^2 = c^2

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 25

The adjacent leg has a length of 5.

tan theta = opp/adj

tan theta = 12/5

The product of these slopes is ______.This product shows that the slopes are negative reciprocals. It is given that the lines ar

Arturiano [62]

Answer:

- 1

Step-by-step explanation:

Let the slope of one line be 's' , then according to the given condition that the slope of second line is negative reciprocal of the first , We obtain the slope of the second line as $\frac{-1}{s}$ .

So, the product of both the slopes is given by $s\cdot \frac{-1}{s}=-1$

This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
