Answer:

The angles are 45°, 60° , 75°

Step-by-step explanation:

<h3>Angle sum property:</h3>

Sum of all the angles of a triangle is 180°.

Equation:  

     3x + 5x + 4x = 180

Combine like terms,

                   12x = 180

                      x = 180/12

                      \sf \boxed{x = 15}

3x = 3 *15 = 45°

5x = 5* 15 = 75°

4x = 4 *15 = 60°

How to multiply a matrices 3x3 by 3x2
lesya692 [45]
The top row of matrix A (1, 2, 1) is multiplied with the first column of matrix B (1,0,-1) and the result is 1x1 + 2x0 + 1x -1 = 0 this is row 1 column 1 of the resultant matrix
The top row of matrix A (1,2,1) is multiplied with the second column of matrix B (-1, -1, 1) and the result is 1 x-1 + 2 x -1 + 1 x 1 = -2 , this is row 1 column 2 of the resultant matrix
Repeat with the second row of matrix A (-1,-1.-2) x (1,0,-1) = 1 this is row 2 column 1 of the resultant matrix, multiply the second row of A (-1,-1,-2) x (-1,-1,1) = 0, this is row 2 column 2 of the resultant
Repeat with the third row of matrix A( -1,1,-2) x (1,0, -1) = 1, this is row 3 column 1 of the resultant
the third row of A (-1,1,-2) x( -1,-1,1) = -2, this is row 3 column 2 of the resultant matrix

PLEASE HELP!!!
ki77a [65]
Part A:
I have attached the graph of this system of inequalities.

Part B:
Plug in (8,10) into both equations

10 > 3(8) + 10
10 > 24 + 10
10 > 34

This is false!

10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7

This is also false!

So, (8,10) is not included in the solution area for the system.
