By using trigonometric relations, we will find that:
sin(θ) = (√33)/7 = √(33/49)
<h3>How to find the value of the sine?</h3>
Remember that for a right triangle, we have the relations:
cos(a) = (adjacent cathetus)/(hypotenuse)
sin(a) = (opposite cathetus)/(hypotenuse).
Here we know that:
cos(θ) = 4/7
Then we can say that we have a triangle with an adjacent cathetus of 4 units and a hypotenuse of 7 units. Now we need to find the other cathetus.
opposite cathetus = √(7^2 - 4^2) = √33
Then we can write:
sin(θ) = (√33)/7 = √(33/49)

Divide both sides of the equation by 0.1 which leaves you with
n = 89.9/0.1 = 899
Answer:
- 3.5(1.6 + 4.6 - 8.5) - 9.75
- = 3.5(-2.3) - 9.75
- = -8.05 - 9.75
- = -17.8
Step-by-step explanation:
- 1.6 + 4.6 - 8.5 = -2.3
- 3.5(-2.3) = 3.5 × -2.3 = -8.05
- -8.05 - 9.75 = -17.8

Answer:
Step-by-step explanation:
on the edge of a cliff overlooking the Pacific ocean. You see a sailboat down in the water below you. The angle of depression to the sailboat is 28◦ . A quick tells you that the cliff you’re standing on is 150ft. How far away from the boat are you, in feet, rounded to one decimal place?(30pts)
We solve using the Trigonometric function of TANGENT
tan 28 = 150/x
