We can use the tangent function for angle 39 to find the value of x.
tan39 = 10/x
x = 10/tan39
x = 12.348
So x is 12.3 rounded nearest to tenth
Answer: Option D.
Step-by-step explanation:
By definition, the absolute value of a number is its distance from 0 on a number line. We know that the distances cannot be negative. Then:
We can assume that the water is at level 0.
We know that the diver dove from a diving platform, which is 4 feet above the water, and then she stopped at -8 feet to pick up some scallops.
This indicates that she stopped at 8 feet below the water.
Therefore, in order to find how far below the diving platform the diver is, we must add 4 feet and the absolute value of -8 feet.
Then, the expression that models this situation is:
Notice that it matches with the expression shown in Option D.
Answer:
It would be to multiply both sides so like you have 9(x-1) = 8(2x + 2)
Step-by-step explanation:
9(x-1) = 8(2x + 2)
9x-9 = 16x+16
and thats the first step

Answer: The ladder should be at least 34 feet long (approximately)
Step-by-step explanation: Please refer to the diagram attached for details.
The chimney is depicted as line AB (33 ft). The distance from the base of the chimney to the ladder is depicted as line BC (3 ft). The ladder is placed such that it forms an angle of 75.5 degrees with the floor. Hence the required length of the ladder needed is shown in the diagram as line AC (line b). The resulting diagram now has an opposite (33 ft) and an hypotenuse (b) which is yet unknown.
To calculate line b, we shall apply the trigonometric ratio as follows;
SinC = opposite/hypotenuse
Sin 75.5 = 33/b
By cross multiplication we now have
b = 33/Sin 75.5
b = 33/0.9681
b = 34.087
Therefore the required length of the ladder is approximately 34 feet.
