The equation is used to solve the value of c is [tex]\rm c = \dfrac{5}{cos35}[/tex], the correct option is c
We have to determine
Which equation can be used to solve for c?
What is the measure of cos angle?
The cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse.
[tex]\rm Cos\theta = \dfrac{Base}{Hypotenuse}[/tex]
Where the measure of the base is 5 and hypotenuse is c and angle is 35 degrees.
Therefore,
The equation that can be used to solve for c is;
[tex]\rm Cos\theta = \dfrac{Base}{Hypotenuse}\\\\\rm Cos35= \dfrac{5}{c}\\\\c = \dfrac{5}{cos35}[/tex]
Hence, the equation is used to solve the value of c is [tex]\rm c = \dfrac{5}{cos35}[/tex], the correct option is c.
