The Reference angle for 302 degree is 58 degree.

<h3 /><h3>What is Reference Angle?</h3>

The acute angle formed by the terminal arm or terminal side and the x-axis is known as the reference angle.

There is always a positive reference angle.

The reference angle is, in other words, the angle formed by the terminal side and the x-axis.

Reference angle is given by

Ф = 360° - Given angle

Ф = 360° - 302°

Ф = 58°

Option A is right answer.

Find the value of each variable. If you give the decimal value, round to the nearest tenth.
DiKsa [7]

u = 10.4 and v = 12

Solution:

In the given 2 sides of a triangle are 60°, 60°.

Sum of all the angles of a triangle = 180°

60° + 60° + third angle = 180°

⇒ third angle = 180° – 60° – 60°

⇒ third angle = 60°

All angles are equal, therefore the given triangle is an equilateral triangle.

⇒ All sides are equal in length.

⇒ v = 12

The line drawn from the top angle divides the triangle into two equal parts

and the line is perpendicular.

12 ÷ 2 = 6

Using Pythagoras theorem,

\text{Base}^2+\text{Opposite}^2=\text{Hypotenuse}^2

⇒ 6^2+\text{opposite}^2=12^2

⇒ 36+\text{opposite}^2=144

⇒ \text{opposite}^2=108

⇒ \text{opposite}=6\sqrt3=10.4

⇒ u = 10.4

Hence, u = 10.4 and v = 12.

Explain why a 3 dimensional figure with a curved surface is not a polyhedron
nekit [7.7K]
Polyhedron, by definition, is formed by intersecting planes, so each part of its surface is either a vertex or an edge, or a flat piece of a plane.
Explanation:
The definition of polyhedron implies that each side is a piece of a flat surface.

juin [17]

We know that the form of line passing through point (x₀ , y₀) and having slope m is : y - y₀ = m(x - x₀)

Here the line passes through the point (-2 ,9)

x₀ = -2 and y₀ = 9 and Given : Slope(m) = -14

Equation of the line :

⇒ y - 9 = -14(x + 2)
