Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c
Explanation:
In order to prove that f is one-to-one and surjective, we can prove directly that f is bijective by findng .
To calculate the inverse of f, first we swap the variables x and y. Then we write y in values of x.
On this step it is important to separate what terms contain y and what terms do not. After that we can separate y as a factor
Thus, . Note that is well defined en every element of B, because it can be defined on any element different from 1, where the divider is zero.
An element of the form , for some x, is an element of A because it is different from -2. Lets suppose that there exist an x such as , thus 2x-1 = -2(1-x) = -2+2x, from where we conclude that 0 = -1, that is a contradiction. As a result, cant be equal to -2.
I hope this works for you!

Answer:
75
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we can find the missing angle by subtracting the measures of the given angles from 180
Thus missing angle = 180 - 34 - 71
180 - 34 - 71 = 75
Which means that the missing angle = 75
