Answer:
135 cm
Step-by-step explanation:
[tex] \cos(43) = \frac{75}{y} [/tex]
[tex]y = \frac{75}{ \cos(43) } [/tex]
[tex]y = 135[/tex]
Answer:
y ≈ 102 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos43° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{75}{y}[/tex] ( multiply both sides by y )
y × cos43° = 75 ( divide both sides by cos43° )
y = [tex]\frac{75}{cos43}[/tex] ≈ 102 cm ( to 3 sf )
