Answer:

<h3>           m∠BAC = 80° </h3>

Step-by-step explanation:

m∠BCD = 145°  ⇒  m∠BCA = 180° - 145° = 35°

From ΔABC:

                    m∠ABC + m∠BCA + m∠BAC = 180°

                         65° +  35° + m∠BAC = 180°

                                  m∠BAC = 180° -  100°

                                   m∠BAC = 80°

A regular octagon has a radius of 6 ft and a side length of 4. 6 ft. A regular octagon has a radius of 6 feet and side lengths o
skad [1K]

The regular octagon has eight equal sides. Then the area of the regular octagon of side length be 4.6 is 102 ft².

<h3>What is a regular octagon?</h3>

It is a polygon that has eight equal sides. In a regular octagon, the opposite sides are parallel. And its diagonals are also equal and intersect at mid-point.

Given

A regular octagon has a radius of 6 ft and a side length of 4.6 ft.

We know the formula for the regular octagon.

Area of the regular octagon = 2(1 + \sqrt{2}) a²

Where a be the side of a regular octagon.

Then the area of the regular octagon will be.

\rm Area = 2 (1+\sqrt{2} ) a^2\\\\Area = 2*(1 + 1.414) *4.6^2\\\\Area = 2 * (2.414)* 21.16\\\\Area = 102.16

Thus, the area of the regular octagon of side length be 4.6 is 102 ft².

More about the regular octagon link is given below.

Q13 A gardener needs to buy compost to fill this tub.
REY [17]

Answer:

  5 bags

Step-by-step explanation:

The volume of the tub is the product of its dimensions:

  V = (1.8 m)(0.5 m)(0.25 m) = 0.225 m³

There are 1000 L in 1 m³, so this volume in liters is ...

  (0.225 m³)(1000 L/m³) = 225 L

At 50 L per bag, the gardener needs ...

  (225 L)/(50 L/bag) = 4.5 bags

The gardener probably cannot purchase a partial bag, so must buy more than is needed.

The gardener must buy 5 bags of compost to fill the tub.
