Answer: tangent

Step-by-step explanation: from the diagram the adjacent and the opposite are given. From SOHCAHTOA , tan is the only trig ratio with opposite and adjacent.

Thus tan teta= opposite÷adjacent

tan teta= 3÷6= 0.5

teta=tan invers of 0.5

=26.6°

A trigonometry student stands 25 meters from a building and measures the angle of elevation to the top of the building as 30â°.

kozerog [31]

Using the slope concept, it is found that the angle measurement has to be within 1.2º of 30º.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

In this problem, considering the horizontal distance and the actual angle, the following equation is applied to find the actual height:

$\tan{30^\circ} = \frac{h}{25}$

$h = 25\tan{30^\circ}$

h = 14.43.

For an error of 5%, the bounds of h are as follows:

$h_{min} = 0.95 \times 14.43 = 13.71$

$h_{max} = 1.05 \times 14.43 = 15.15$

Hence, the angles will be given by:

$\tan^{\alpha} = \frac{13.71}{25}$

$\alpha = \tan^{-1}{\left(\frac{13.71}{25}\right)}$

$\alpha = 28.8$

$\tan^{\alpha} = \frac{15.15}{25}$

$\alpha = \tan^{-1}{\left(\frac{15.15}{25}\right)}$

$\alpha = 31.2$

Hence the angle measurement has to be within 1.2º of 30º.

jill is training for a marathon and runs 2 1/3 miles three times a week how far will she run in six weeks

Nostrana [21]

Answer:

Step-by-step explanation:

42 times

first, you do 2 1/3 times 3, which is 7. That means 7 miles in one week. then, you do the number of miles times the number of weeks. So, that is 7x6 which is 42.
