Step-by-step explanation:
Answer:
162
Step-by-step explanation:
2, 2*3, 2*3*3, 2*3*3*3, 2*3*3*3*3=162
Answer:
total measure of circle = 360 degree
AB = 70 DEGREE
BC = 104 DEGREE
THEREFORE AD + DC + AB + BC = 360
AD+DC =360 – 70 – 104
AD + DC = 186 degree
Now,
ADC = 186 DEGREE
X = number of singles matches
y = number of doubles mnathes
so we have the equation x + y = 13.......(1)
also
2x + 4y = 38 ...........(2)
(1) and (2) are the required equations
b) Find how many maches are in progress by solivng the above equations:-
x + y = 13 multiply this by -2:-
-2x - 2y = -26
2x + 4y = 38 Adding to removes the terms in x:-
2y = 12
y = 6
so x = 13-6 = 7
So the answer is 6 double matches and 7 singles are in progress.
