What are the coordinates of Y(-3.5,5) Across the x-axis?

Mathematics

Elenna [48]3 years ago

I'm assuming you are asking what the coordinates would be if they were reflected across the x-axis. 

The answer to that is (-3.5, -5). When you reflect across the x-axis, the y-coordinate will change signs. And when you reflect across the y-axis, the x-coordinate will change signs.

An angle measured 10 degrees less than the measure of its complementary angle. Find the measure of both angles
Mazyrski [523]

Answer:

The measure of the angles are 40 degrees and 50 degrees

Step-by-step explanation:

Let

x ----> the measure of one angle in degrees

y ----> the measure of the complementary angle in degrees

we know that

If two angles are complementary, then their sum is equal to 90 degrees

so

x+y=90 ----> equation A

we have that

x=y-10 ----> equation B

Substitute equation B in equation A and solve for y

(y-10)+y=90\\2y-10=90\\2y=100\\y=50

Find the value of x

x=50-10=40

therefore

The measure of the angles are 40 degrees and 50 degrees

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t
xxMikexx [17]
If we let
x as the distance traveled by the boat
y as the distance between the boat and the lighthouse.

Then, we have:
tan 18°33' = 200 / (x + y)
and
tan 51°33' = 200 / y

Solving for y in the second equation:
y = 200 / tan 51°33'

Rearranging the first equation and substituting y
x = 200 / tan 18°33' - 200 / tan 55°33'
x = 458.81 ft

Therefore, the boat traveled 458.81 ft before it stopped.
