Step-by-step explanation:
Answer:
D Point A
Step-by-step explanation:
The vertex is where the two sides of the angles come together
A is the vertex of the angle
In three dimensions, the cross product of two vectors is defined as shown below

Then, solving the determinant

In our case,

Where we used the formula for AxB to calculate ixj.
Finally,

Thus, (i+j)x(ixj)=i-j
Answer:
See explanation
Step-by-step explanation:
(4)
Using the sine ratio in the right triangle
sinΘ =
=
, thus
Θ =
(
) ≈ 51.1°
(5)
Using the tangent ratio in the right triangle
tanΘ =
=
, thus
Θ =
(
) ≈ 38.7°
Answer:
Step-by-step explanation:
this seems like substitution
If so its the first part is 12x6
second part is 35 x 6
third part is 56 x 6
