Explanation

A reflex angle is any angle greater than 180° but less than 360°.

215° fits this definition.

Explanation

Area of parallelogram = base × height = 16 × 9 = 144 cm²

Area of square = side² → side = √144 = 12 cm

Explanation

An isosceles triangle has two sides equal in length.

It also has two equal angles opposite those equal sides.

Explanation

An angle less than 90° is called an acute angle.

Exactly 90°: Right angle

Between 90° and 180°: Obtuse angle

Exactly 180°: Straight angle

More than 180° and less than 360°: Reflex angle

Explanation

The angle θ can be found using tan(θ) = height / shadow length, i.e., tan(θ) = 3 / √3 = √3.

Since tan 60° = √3, the angle between the ground and the Sun is 60°.

Explanation

To find the surface area of the cylinder:

Use the formula:

Surface Area = 2πr(h + r)

where r = 7 cm and h = 33 cm:

Surface Area = 2π(7)(33 + 7)

= 2π(7)(40)

≈ 2 × 3.14 × 7 × 40

≈ 1760 cm²

Explanation

A square has four equal angles, and each angle measures 90 degrees.

It’s a property of all regular quadrilaterals.

Explanation

The radius is half of the diameter, so: 16 cm ÷ 2 = 8 cm.

Radius is the distance from the center of the circle to any point on its edge.

Explanation

Mohammad Ashraf Ghani Ahmadzai [a] (born  May 19, 1949) was the fifth president of Afghanistan and the second and last president of the Islamic Republic from September 2014 to August 2021. A politician, academic and economist.

Explanation

A square has four equal sides, so the perimeter is 4 times one side.

If L is the length of a side, then Perimeter = 4L.
