Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65
For matrix subtraction, you subtract the corresponding cell of the second matrix from the first. So, looking at the first spot, you have 4 (from the first matrix) - 4 (from the second matrix) = 0 (the first number in the output matrix). Continuing that for the next spot, -4 - -3 = -4 + 3 = -1. Finally, -2 - 5 = -7. This means your answer is [0 -1 -7].
The answer to this is 3/4.
