Answer:
a +(b -c) = -9i +10j
Step-by-step explanation:
You can use the distributive property to remove the parentheses:
a +(b -c) = a + b - c
Add the vectors as though they were binomials.
a + b - c = (3 -2 -10)i +(4 +5 -(-1))j = -9i +10j

Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
