Complementary angles = two angles that add to 90° complement each other.
So, angle x = 3y+18
y= complementary angle
(3y + 18) + y = 90
4y+18 = 90
4y=72
y=18°
x= 3y+18
x= 3(18) +18
angle x = 72°
3 cm because the radius is 1.5 cm and the diameter is the radius times 2
5/6 pages of a book in a minute!
8 1/3= 25/3= amount in 10 minutes
25/3 x 1/10=25/30=5/6
I got 1/10 when I did reciprocal(meaning flip the number over, the numerator goes on the bottom, and the denominator goes on the top)
10x 1/10= 1
