as , 77+x = 146(external angle) , so x = 146 - 77
so x = 69
Circumference of a circle = 2πr
Circumference of the whole circle= 2π(30) = 60π
360 - 90 = 270
Length XPY = 270/360 x 60π = 45π
Answer: 45π m
Y=-2x+0 haahahaha hope i helped i think
So five times five is twenty five. Then do three times fifteen which is forty five.
25+45=70
the answer is 2x2+12z-5 (its also in the picture)
