If you multiply a matrix and its inverse together, you will always get the identity matrix.
True
False

True

Step-by-step explanation:

If you multiply a matrix (such as A) and its inverse (in this case, A–1), you get the identity matrix I. And the point of the identity matrix is that IX = X for any matrix X (meaning "any matrix of the correct size", of course).

Yes

Step-by-step explanation: And 1 is the identity, so called because 1x = x for any number x. It works the same way for matrices. If you multiply a matrix (such as A) and its inverse (in this case, A–1), you get the identity matrix I.

The trigonometric function that can be use to solve for the height (h)  is tanФ = opposite / adjacent

The height of the kite is 221.72 feet

Step-by-step explanation:

The trigonometric function that can be use to solve for the height (h)  is tanФ = opposite / adjacent

To solve for height h of the kite, we will follow the steps below;

We will use the trig. function

tanФ = opposite / adjacent

from the diagram given Ф = 29°    opposite  = h     and adjacent = 400 feet

tan 29°  =  h  /  400

cross-multiply

h = 400 tan 29°

h =221.72 feet

The height of the kite is 221.72 feet
