Answer: 69
Step-by-step explanation:
The two angles are a linear pair, which means that they lie on the same line. Therefore, you just have to substract angle 1 with 180.
180-111=69
Write it in y= mx+b form. Subtract 5x from both sides to get 4y = -5x + 100. Divide by 4 so the answer would be y= -5/4x + 25.
Unsure of what you want.
If you are merely to mult. the 3x3 matrix by -8, then mult. every one of the 9 elements in the first matrix by -8. That's it.

Answer:
n=2
Step-by-step explanation:
25n=2×25
Divide each side by 25
25n/25=2×25/25
n = 2 * 25/25
n =2
Answer:
sum of all angle of triangle is equal to 180 degree
X + 34 + 31 =180
x+65=180
x=180-65
x=115
