b. 29i-20
c.-21i
d.29
Answer:
The value of the (2 – 5i)(p + q)i is 29i .
Option (a) is correct .
Step-by-step explanation:
As the expression given in the question.
= (2 - 5i) (p + q)i
Simplify the above
= (2 - 5i) (pi + qi)
= 2pi + 2qi - 5pi²- 5qi²
As i² = -1
Put in the above
= 2pi + 2qi + 5p +5q
= 2i × 2 + 2i × 5i + 5 × 2 + 5 × 5i
= 4i + 10i² + 10 + 25i
As i² = -1
= 4i - 10 + 10 + 25i
= 29i
Thus the value of the (2 – 5i)(p + q)i is 29i .
Option (a) is correct .

70
40
50
Answer: the correct option is (C) 40.
Step-by-step explanation: As shown in the attached figure below, the line OF bisects the angle EOG, where
We are to find the value of y.
Since OF is the bisector of the angle EOG, so it divides the angle EOG into two congruent angles.
Therefore, we get
Thus, the value of y is 40.
Option (C) is CORRECT.
