Answer:
(1- cose0)(1 + cose0) = 0
(1-sin0)(1+sin0) = 1
Step-by-step explanation:
(1- cose0)(1 + cose0) = 0
1st Simplify: \left(1-cos(0))(1+cos(0))
2nd Use the following trivial identity: (0\right)=1
=(1-1)(1+1)
3rd Simplify:(1- cose0)(1 + cose0) = 0
___________________________________________________
(1-sin0)(1+sin0) = 1
1st Use the following trivial identity: sin(0)=0
(1 - 0) (1 + 0)
2nd Simplify: (1-sin0)(1+sin0) = 1
$250 - $5x = Amount of Money left
Hope this helps!
The point where the lines intersect is the solution to the system of equations.
(x, y) = (2, 3)
Answer:
B. The statement is false. This is true only if θ is an acute angle in a right triangle.
Step-by-step explanation:
Trigonometric ratio formula can only be applied to define the relationship between the angles of a right triangle and its side lengths.
Therefore, it is impossible to define or find the tan θ of "any triangle". It only applies to right angled triangles.
In the case of a right triangle, given a reference angle, θ, tan θ = side lenght opposite to θ ÷ side lenght adjacent to θ (tan θ =
.
A right triangle has two acute angles and 1 right angle that which is 90°.
Therefore, we can conclude that:
"B. The statement is false. This is true only if θ is an acute angle in a right triangle."
