option B
Cos theta is positive and sin theta is negative in quadrant IV
We have to find opposite side using Pythagorean theorem.
x² + 4² = 5²
x² + 16 = 25
x² = 25- 16
x² = 9
A diagram would surely help here. But imagine that you stand at spot A and someone finds that your distance from the base of the building is 42 feet. Call this point B.
Imagine a vertical line from that spot, straight up. Label the top of this line C.
The acute angle at A is 67 degrees. You want to find the height of the building, which would be the length of the "opposite side of triangle ABC."
The length of the "adjacent side of triangle ABC" would be 42 feet.
We don't know the length of the hypotenuse, altho' we could easilyl calculate it using the Pyth. Them.
We choose the tangent function to solve for the height of the building (which is the length of the opposite side.
height
By definition, tangent (67 degrees) = -------------------------------------
42 feet
Find tan 67. Multiply your result by 42 feet. This product is the height of the building.
Answer:
j=-37
Step-by-step explanation:
step 1
Find the slope of the given line
we have
Convert to slope intercept form
Isolate the variable y
subtract 2x both sides
divide by 3 both sides
The slope is
step 2
we have the points
(2,-9) and (j,17)
Find the slope
The formula to calculate the slope between two points is equal to
substitute
Remember that
If two lines are parallel then their slope are equal
therefore
The answer is to this question is :
x=-5
Answer:
yes the statement is true
Step-by-step explanation:
if you plug in 1^2 you are just multiplying 1 by its self
