sin 30° = 5/x and x = 2.5. We can find the length side of the side labeled x with the equation sin 30° = 5/x where x = 2.5.
This problem can be solved by using trigonometry, which is part of the mathematics that studies the relationships between the sides and angles of a triangle.
Using the equation sin θ = opposite leg/hypotenuse, with θ = 30°, opposite leg = 5, and hypotenuse = x.
sin 30° = 5/x (Part A)
To find x:
x = sin 30° (5) = (0.5)(5)
x = 2.5 (Part B)
Answer:
A
Step-by-step explanation:
slope=y/x=-3/(-4)=3/4
90. the 7 causes it to round up (it is closer to 90 than it is to 80).
