Angle ABC is a straight angle. m∠DBC = 130° and BE bisects ∠ABD.<br><br><br> What is mEBA?
seraphim [82]
The answer:

we observe that <span>m∠DBC = 130° 
</span><span>
we should find the value of </span>mEDB to answer this question
Angle ABC is a straight angle, so m ABC= 180°, but 
mABD  + <span>m∠DBC = 180° (look at the figure)
</span>
so mABD= 180° - m∠DBC = 180 - 130 = 50°

therefore, mABD= 50°,
and BE bisects ∠ABD imiplies  mEBA = mEDB, and mABD=  mEBA + mEDB= 50°, it does mean 2x mEBA = 50°

and from where mEBA = 50°/2=25°

Matrix A is said to be involutory if A2 = I. Prove that a square matrix A is both orthogonal and involutory if and only if A is
goblinko [34]

Answer:

4 · 1/4 (I-0) = (A-0)∧2

see details in the graph

Step-by-step explanation:

Matrix A is expressed in the form A∧2=I

To proof that Matrix A is both orthogonal and involutory, if and only if A is symmetric is shown by re-expressing that

A∧2=I in the standard form

4 · 1/4 (I-0) = (A-0)∧2

Re-expressing

A∧2 = I as a graphical element plotted on the graph

X∧2=I

The orthogonality is shown in the graphical plot displayed in the picture. Orthogonality expresses the mutually independent form of two vectors expressed in their perpendicularity.
