Answer:
x = 16
Step-by-step explanation:
11 + x + 13 = 40
x + 24 = 40
x = 40 - 24
x = 16
Thus, The value of x is 16

Answer:
∠ 4 = 130°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle , so
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 9 = 6x + 6 + 4x + 14 , that is
11x + 9 = 10x + 20 ( subtract 10x from both sides )
x + 9 = 20 ( subtract 9 from both sides )
x = 11
Then
∠ 4 = 11x + 9 = 11(11) + 9 = 121 + 9 = 130°
your friend may have only calculated ∠ 1
∠ 1 = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°
The amplitude of this function is 4/5. Be sure you understand why that is so.
X-y=34
x+y=338
We can use elimination in this problem.
2x=372
x=186
186+y=338
y=338-186
y=152
