The answer is option C) 19,-19
<u>Step-by-step explanation</u>:
Given, z² = 361
To eliminate the square of z, take square root on both sides
z = √361
- The factor of 361 could not be an even number, since the last digit of 361 is odd. So, eliminate option A)
- The option B) is a larger number and it cannot be the answer. So, eliminate it.
- Try option C) works or not. (19)² = 19
19 = 361 and (-19)² = -19
- Therefore, z = √361 = ±19. option C) is the correct answer.
Answer:
Step-by-step explanation:
APB is a straight line.
Using liner pair(sum of angles on straight line is 180 degree)
But
In triangle FPD, FP=DP (radius of same circle.
So, triangle FPD would be isosceles triangle. FD is base of triangle.
PE is perpendicular to FD.
As we know angle bisector of isosceles triangle make perpendicular to base.
So, line PE bisect angle FPD.
As we found above
So,
