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: x < 2
Step-by-step explanation:
12 - 5x > 8 - 3x
Now, add 5x on both sides
12 - 5x + 5x > 8 - 3x + 5x
12 > 8 + 2x
Now, subtracting by 8 on both sides
12 - 8 > 8 - 8 + 2x
4 > 2x
Now, dividing by 2 on both sides
4/2 > 2x/2
2 > x, which is same as x < 2.
Bob should by the 25cm cake for 18.75 each. He will need to buy 3 of these cakes in order to feed 57 guests. The total cost would be 56.25. If he were to buy the 20cm cake, he would need to purchase 5 cakes for a total of 67.50.
10^2+15^2=
100+225=325
The square root of 325 is 18.0277563773 is you round it to the hundredths place it’s 18.03
