Answer: 27/12=2.25
Pretty simple:)
Step-by-step explanation:
The interior angles of a triangle add up to 180 degrees
a = 1st angle, b = 2nd angle, c = 3rd angle
c = 6a
b = a + 60
a + b + c = 180
a + (a + 60) + (6a) = 180
8a + 60 = 180
8a = 180 - 60
8a = 120
a = 120/8
a = 15 <=== here is one angle
b = a + 60
b = 15 + 60
b = 75 <=== and another one
c = 6a
c = 6(15)
c = 90 <=== and the last angle
Answer:
9 inches
Step-by-step explanation:
The radius is 1/2 of the diameter
r = d/2
r = 18/2 = 9
2x^2 + 14x + 12 = 0
x^2 + 7x + 6 = 0
( x + 1 )( x + 6 ) = 0 ==》 x = - 1 Or x = - 6
Answer:
62.5%
Step-by-step explanation:
150/240=0.625
you do 0.625x100 to get the percent.
