Answer:

Angle of elevation = 21.167°

Step-by-step explanation:

Given:

Horizontal distance cover by rover = 180 m

Vertical distance cover by rover = 65 m

Find:

Angle of elevation

Computation:

Using trigonometry function;

Sin θ = Perpendicular / Hypotenuse

⇒ Sin θ = Vertical distance cover by rover / Horizontal distance cover by rover

⇒ Sin θ = 65 / 180

⇒ Sin θ = 0.3611

⇒ Sin⁻¹ (0.3611) = 21.167°

Angle of elevation = 21.167°

The temperature change on the second day is greater than the temperature change on the first day.

<h3>What is temperature change?</h3>

The term temperature change refers to the difference in the temperature between the sunrise and the sunset. The temperature at sunrise and sunset are shown in the table attached to this answer.

The change in temperature on the first day is;

13.49 - (-11.31) = 24.80

The change in temperature on the second day is;

25.25 - (-7.69) = 32.94

Thus, the temperature change on the second day is greater than the temperature change on the first day.

Find the value of x <br> (8x-1) (4x+7)

Helen [10]

Answer:

The value of x = 7

Step-by-step explanation:

Given the right triangle

Right angle = 90°

α = (4x+7)°

β = (8x-1)°

We know that the sum of angles of a triangle is 180°.

Right angle + α + β = 180°

90° + 4x+7 + 8x-1 = 180

Group like terms

$4x+8x+90+7-1=180$

Add similar elements: :4x+8x=12x

$12x+90+7-1=180$

$12x+96=180$

$12x=84$

Divide both sides by 12

$\frac{12x}{12}=\frac{84}{12}$

$x = 7$

Therefore, the value of x = 7
