We have 2 intersecting chords so:
Whenever 2 chords intersect,
Angle AED = Angle BEC = 66 degrees
66 degrees = .5 * (arc AD + Arc BC)
66 degrees = .5 * (arc AD + Arc BC)
66 degrees = .5 * (54 + Arc BC)
66 degrees -27 = .5 Arc BC
39 degrees = .5 Arc BC
Arc BC = 78 degrees
So, you are correct Ranya2

How many solutions does the equation 6a − 3a − 6 = −2 + 3 have?
Bogdan [553]

Answer:

One.  It is a = 7/3

Step-by-step explanation:

Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:

3a - 6 = 1

Adding 6 to both sides, we get:

3a = 7.

Dividing both sides by 3, we get

a = 7/3.

This equation has ONE solution, which is a = 7/3.

What is the area of this figure?
Gelneren [198K]

Area of the figure is 102 cm²

Step-by-step explanation:

  • Step 1: Find the area of the square with side = 6 cm.

Area of the square = (side)² = 6² = 36 cm²

  • Step 2: Find the area of the trapezoid.

Length of parallel side 1 = 7 cm

Length of parallel side 2 = 21 - 6 = 15 cm

Height = 6 cm

⇒ Area of the trapezoid = 1/2 × (Sum of parallel sides) × height

                                        = 1/2 × (7 + 15) × 6

                                        = 1/2 × 22 × 6 = 66 cm²

  • Step 3: Find the area of the figure.

Area of the figure = Area of the square + Area of the trapezoid

                             = 36 + 66 = 102 cm²
