Answer:

53 degrees to the nearest degree.

Step-by-step explanation:

Sine  H = opposite / hypotenuse

= 8/10

= 0.8

H = 53 degrees.

Answer:

H=53\degree

Step-by-step explanation:

All the lengths of the sides of the given right angle triangle is given.

We can use any of the basic trigonometric ratios to find angle H.

Recall that;

\sin(H)=\frac{Opposite}{Hypotenuse}

\sin(H)=\frac{8}{10}

\sin(H)=0.8

We take the inverse sine of both sides to get;

H=\sin^{-1}(0.8)

This implies that

H=53.1\degree

H=53\degree to the nearest degree.

just olya [345]

Answer:

49°

Step-by-step explanation:

Given vectors:

a = [-8, 6]

B = [√7, 3]

θ = ?

To find the angle between the two vectors, we will be using the formula,

                                   a.B = |a||B|cosθ

For simplicity, it is good to first calculate the dot product, and the magnitudes. Then we will substitute the values of the dot product, and the magnitudes of the vectors to solve for the angle.

Calculating the dot product

         a.B = (-8, 6) . (√7, 3)

               = (-8 × √7) + (6 × 3)

               = -8√7 + 18

               = 18 - 8√7

               = 10√7

Calculating the magnitude the vectors

1. The magnitude of vector (-8, 6)    

                |a| = \sqrt{(-8)^{2} + 6^{2}}

                |a| = \sqrt{64 + 36}

                |a| = \sqrt{100}

                |a| = 10

2. The magnitude of vector (√7, 3)

                |B| = \sqrt{(\sqrt{7})^{2} + 3^{2}}

                |B| = \sqrt{7 + 9}

                |B| = \sqrt{16}

                |B| = 4

Calculating the angle between the vectors,

                cosθ = \frac{a.B}{|a||B|}

                cosθ = \frac{10\sqrt{7}}{10 * 4}

                cosθ = 0.6614

                θ = cos⁻¹0.6614

                θ = 48.59°

                θ = 49°

Answer:

The third one (parabola)

Step-by-step explanation:

Do a vertical line test.

Basically draw vertical lines over the function. If the x-value has more than one y-value then it is a relation and not a function
