Answer:
( -10j ) + 3.
Step-by-step explanation:
-5j + ( 2j ) + 3 - 5j + ( -2j ) (Collect all similar entities with the same +/- sign)
= -5j -5j -2j + 3 + 2j (Sum up all entities regardless of the sign)
= -12j + 3 + 2j (resolve using basic arithmetics)
= -10j + 3

Step-by-step explanation:
Answer:
a = 49°
Step-by-step explanation:
OB = OC ( both radii of the circle ), thus
Δ BOC is isosceles and the base angles are congruent, that is
∠ OBC = ∠ OCB = 41° , so
∠ BOC = 180° - (2 × 41)° = 180° - 82° = 98°
The angle on the circumference BAC is half the angle at the centre for angles subtended on the same arc , thus
a = 0.5 × 98° = 49°
