An exterior angle of a triangle is an angle formed by one side of the triangle and the extension of an adjacent side of the triangle.
FACTS:
- Every triangle has 6 exterior angles, two at each vertex.
- Notice that the "outside" angles that are "vertical" to the angles inside the triangle are NOT called exterior angles of a triangle.
1. Angles 1, 5 and 6 are inteior angles of the given triangle.
2. Angle 3 is vertical to the interior angle 5.
3. Angles 2 and 4 are exterior angles of the triangle.
Answer: correct options are A and B.
I baseball player swung at the ball 100 times and only made conract 75 times this could be exspressed as 0.75

Answer:1.3
Step-by-step explanation:
The plane we want to find has general equation
with 
not equal to 0, and has normal vector
is perpendicular to both the normal vector of the other plane, which is 
, as well as the tangent vector to the line 
, which is 
.
This means the dot product of with either vector is 0, giving us
Suppose we fix 
. Then the system reduces to
and we get
Then one equation for the plane could be
or in standard form,
The solution is unique up to non-zero scalar multiplication, which is to say that any equation 
would be a valid answer. For example, suppose we instead let 
; then we would have found 
and 
, but clearly dividing both sides of the equation
by 2 gives the same equation as before.
