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
Answer: 12/5
Answer:
7 minutes
Step-by-step explanation:
1000 stairs in 25 minutes
280 stairs in 280*25 / 1000 = 7 minutes
X+y=70
x-y=30
x=30+y
30+y+y=70
2y=40
y=20
x+20=70
x=50
xy=(50)(20)=1000
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
.
So, the product of both the slopes is given by 
This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1
