We are given that the angle a is the right angle. So let
us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the
hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or
angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration
of the triangle.
Answer:
The answer is -5/3
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- x₁ = 0 and x₂ = (-3)
- y₁ = 9 and y₂ = 4
Slope of a line
Now,
m = y₂ – y₁ ÷ x₂ – x₁
m = 4 – 9 ÷ 0 – (-3)
m = -5 ÷ 3
m = -5/3
Thus, The slope is -5/3

Step-by-step explanation:
please give me brainlest
So how many does he have left
25-16=9
9 floors left
the want a percentage so 9 out of 25
percent is out of 100
a hack for this specific problem is that 25 is exactly 1/4 of 100 so
9/25 times 1=the same thing so
9/25 times 4/4 (simplifies to 1)=(9 times 4)/(25 times 4)
36/100
this is out of 100 so
36%
of course there is a legit way of solving this problem but this is a hack (this works for factors of 100 like 2,4,5,10,20,25,50)
Answer:
4
Explanation:
Since the third term is the sum of the two previous terms
Continuing in like manner
Since
Recall:
The sequence is therefore:
8,-5,3,-2,1,-1,0
The sum of the seven numbers is 4.
