Answer:
Step-by-step explanation:
B = 2/5(A - 9)
(5/2)B = A - 9
A = 9 + (5/2)B
Answer:
3’5”
Step-by-step explanation:
14/4
The situation can be expressed with the following.
P=550-127
Answer:
see explanation
Step-by-step explanation:
Since AB = BC the the triangle is isosceles and thus
∠ A = ∠ C = 8x
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
44x + 8x + 8x = 180, that is
60x = 180 ( divide both sides by 60 )
x = 3
Thus
∠ A = ∠ C = 8x = 8(3) = 24°
∠ B = 44x = 44(3) = 132°
The third choice.
The sides of the photo plus the margins of the border equal x.
