Answer:
E. is 103 degree.
It's a vertical angle.
F. is 77 degree
the e and f makes a 180 degree. 180-103(aka e) = 77 degree
D. is 90 degree. it's perpendicular.
3562 is greater than 979, 3562>979 Because 3562 is bigger than 979. (Did this help?)
You know that a circle has an angle of 360 degrees. Also, you know that when two lines intersect, their interior angles are the same. So you are given angle BPD and angle CPA equals 146 and 164 respectively. The measure of angle BPD is 146 degrees
Y=10x+20
10x because the price is $10 a class
+20 because it costs $20 for the monthly subscription
Q1:-
-------
12*12= 144
11*11=121
so the answer of 1. lies between 11 and 12
Q2:-
--------
9*9=81
10*10=100
so sqrt(82) is between 9 and 10
