Answer:
y=12
Step-by-step explanation:
5 is half of 10 so there for y is always half of x in this problem
Answer:
Step-by-step explanation:
a)
the sum of all angles in a quadrilateral must be 360º
y+88+25+35 = 360
y = 360=88-25-35
y = 212º
b)
the sum of all angles in an octagon must be 1080º
45+45+140+140+6y = 1080
6y = 1080-90-280
6y = 710
y = 710/6
y=~ 118,3º
B)m=-1
C)m=14
D)m=-8=-+sqrt33
The equation for the circle is:
(x-8)^2 + (y-1)^2 = 49
If we take 'y' as 1, then
(x-8)^2 + 0 = 49
x-8 = √49
x = ±7 + 8
x = 15 or x = 1
b) x (2x^2 + 4x + 1)
c) 2x (x^2 + 2x - 1)
d) x (2x^2 + 4x -1)
