Answer:
44°
Step-by-step explanation:
Note that the square in located to the left of the two given intersecting lines denotes that it is a right angle, in which the measurements is 90°.
This means that:
∠α + ∠β = 90°
Let:
m∠α = x
m∠β = 46°
Plug in the corresponding numbers and variable to the given terms:
x + 46 = 90
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 46 from both sides:
x + 46 (-46) = 90 (-46)
x = 90 - 46
x = 44
x = 44° is your answer.

Answer:
0.2x + y -6
Step-by-step explanation:
A and b are already there but to get c you just have to move 6 to the other side by subtracting it from the right side and adding it to the end of the left side.
The answer is 11 and 12, because if you add them you get 23 and if you subtract them you get 1.
Let Bea = x
Therefore Andrew = x + 2
Chris = x - 3
Andrew * Chris = 66
(x + 2)(x - 3) = 66 Remove the brackets.
x^2 + 2x - 3x - 6 = 66
x^2 - x - 6 = 66 Subtract 66 from both sides.
x^2 - x - 72 = 0
(x - 9)(x + 8) = 0
Find the possible values of Bea's age
x - 9 = 0
x = 9 That value works. She can be plus 9 years old.
x + 8 = 0
x = - 8. There's no way she can be - 8 years old
So Bea is 9.
