Answer:
Two planes always would intersect at a line, as shown in attached figure below.
Step-by-step explanation:
As we know that
A plane has basically 2 dimensions.
But as the plane is infinitely large, we can say that length and width of a plane is not supposed to be measured. (can not be measured)
Let suppose we have a pair of intersecting planes.
If If two intersecting planes are not parallel, then they would intersect each other somewhere.
BUT
Two planes always would intersect at a line, as shown in attached figure below.
Four holes I believe.
Just a wild guess though.
Answer:
(-2,3)
Step-by-step explanation:
Multiply -3x+4y=18 with 2:
-6x+8y=36
Add -6x+8x=36 and 6x+2y=-6
10y=30
y=3
So y=3 we can replace y with 3 on any of these two equations:
6x+6=-6
Move the 6 to the other side:
6x=-12
x=-2
So the solution is
(-2,3)
Hope this helps

Answer:

Step-by-step explanation:
In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.
Therefore, we have the following equation:

Solving, we get:

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.
Using the Pythagorean theorem to verify our answers:
