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:
i think it 36 sorry if it wrong tho have a nice day
Step-by-step explanation:
Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note:
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)
Answer:
(Negative two-fifths) (Negative StartFraction 8 over 9 EndFraction) (one-third) (StartFraction 2 over 7 EndFraction)
Step-by-step explanation:
(Negative two-fifths) (Negative StartFraction 8 over 9 EndFraction) (one-third) (StartFraction 2 over 7 EndFraction) = (-2/5)(-8/9)(1/3)(2/7)
Let's take the fraction and eliminate the negative sign because negative multiply negative= positive
(-2/5)(-8/9)(1/3)(2/7)= 32/945
Hello again!
We have this equation
x³ - 4x² + 2x + 10 = x² - 5x - 3
All we have to do is follow the steps that we know and remember, when you are doing Algebra make you used the easiest away. You can repeat the same steps over and over as long your answer is correct.
OMG I talked too much!
Ok let's solve this
x³ - 4x² + 2x + 10 = x² - 5x - 3
x³ - 4x² + 2x + 10 -x² -5x - 3 = 0
Now again, all we have to do is factorize. Be very careful when you are factorizing.
(x +1)(x² - 6x + 13) = 0
Set factors equal to 0
x + 1= 0 or x² - 6x + 13 = 0
x = -1
This is the answer!
Wait !
I didn't solve x² - 6x + 13 = 0 but I already know I will ended up having NO REAL SOLUTION!
I hope this help again!
A+ Guaranteed! Feel free to comment or message me if you have further questions about the answer.
