Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
?=115-50=65°
Answer: D) 12
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The greatest common factor is 12.
A) x/y = 2/3
B) x + y = 105
Solving Equation A for y
A) y = 1.5x
Substituting A into B
B) x + 1.5x = 105
2.5x = 105
x = 42
y = 63
Answer:
b option im not sure but
Step-by-step explanation:
The circumference of a circle is calculated through the equation,
C = 2πr
where C is circumference and r is radius. For this item, I assume that 12 in is the radius such that,
C = 2π(12 in) = 24π
Thus, the circumference of the circle is 24π inches.
