M∠A = 133°.
Opposite angles in an inscribed quadrilateral are supplementary, so we have
(4x+5)+(x+15) = 180
Combining like terms gives us
5x + 20 = 180
Subtract 20 from both sides:
5x+20 - 20 = 180 - 20
5x = 160
Divide both sides by 5:
5x/5 = 160/5
x = 32
Substitute this into our expression for ∠A:
4(32) + 5
128 + 5
133
Answer:
Step-by-step explanation:
We are given that vector space of all symmetric matrix
M(R)={
where a,b,c,d,e,f,g,h,i}
Let A=
A'=
A is symmetric
Then A'=A
=
a=a , e=e, i=i
a-a=0 , e-e=0, i-i=0
b=d, c=g ,f=h
Hence, the matrix
Therefore, the basis are
There are three elements to generate an element of vectors of all symmetric matrix matrix
=
Answer:
Parent's share would be : 28%
Step-by-step explanation:
Cost of the computer = $2000
Anya's share = $1200
Brother's share = $240
Parents paid rest. That will be : 2000 - 1200 - 240 = $560
Percentage of parents share :
