Answer: 192.. just took the test :)
Step-by-step explanation:
x^3=54 (Subtract 3 from both sides)
x = 3rd power cube root of 54 (Cube root both sides)
27 = 3^3 (3x3x3) therefore
x = (3) (3rd power cube root of 2)

Answer:
9f
Step-by-step explanation:
Answer:
x = 64°
∠A = 88°
∠C = 92°
Step-by-step explanation:
This is a cyclic quadrilateral, since every vertex of the quadrilateral touches the circumference of the circle.
The opposite angles in a cyclic quadrilateral add up to 180°
∠B is opposite to ∠D
⇒ ∠B + ∠D = 180
⇒ 116 + x = 180
⇒ x = 180 - 116
⇒ x = 64°
If x = 64°, then
⇒ ∠A = (2 x 64) - 40
⇒ ∠A = 88°
∠A is opposite to ∠C
⇒ ∠A + ∠C = 180
⇒ 88 + ∠C = 180
⇒ ∠C = 180 - 88
⇒ ∠C = 92°
