C.Is a right triangle because a2+b2=c2


If you do 33^2+56^2=65^2

33^2=1089 56^2=3136. Add that together equals 4225 and if you do 65^2 it equals 4225 which would mean it is a right triangle

QS bisects $\angle PQR$ and $m\angle PQR\ =\ 119\degree$ .
deff fn [24]

Answer:

Step-by-step explanation:

Id QS bisects angle PQR, then <PQS = <SQR and <PQS+<RQS = <PQR

The formula then becomes

<PQS+<PQS = <PQR

2<PQS = <PQR

<PQS = <PQR/2

Given <PQR = 119°

Substitute into the resulting expression above;

<PQS = <PQR/2

<PQS = 119/2

<PQS = 59.5°

Since <RQS = <PQR, hence <RQS is also 59.5°

Please explain, thanks! :)<br><br> Multiply DE

First, we have to make sure that the number of columns in the first matrix is equal to the number of rows in the second matrix.

\left[\begin{array}{cc}1&-3&2&0\\\end{array}\right] *   \left[\begin{array}{ccc}2&3&4\\1&2&3\end{array}\right]

Since this is true, we can continue to solve the problem.
To multiply two matrices, multiply each row element in the first matrix by each column element in the second matrix. For example:
1*2 = 2
-3*1=-3
Then we add them to get our new matrix element.
-3+2=-1
Then we move to the next column of the second matrix.
1*3=3
-3*2=-6
-6+3=-3
Then the final column of the second matrix.
1*4=4
-3*3=-9
-9+4=-5
Our matrix so far:
\left[\begin{array}{ccc}-1&-3&-5\\x&x&x\end{array}\right]
We do the same for the bottom row of the first matrix.
<em>First Column</em>
2*2=4
0*1=0
4+0=4
<em>Second Column
</em>2*3=6
0*2=0
6+0=6
<em>Third Column</em>
2*4=8
0*3=0
8+0=8
Our final matrix is:
\left[\begin{array}{ccc}-1&-3&-5\\4&6&8\end{array}\right]
