What is the angle of elevation of the sun when a 44-ft mast casts a 14 ft shadow?

Naya [18.7K]

Step-by-step explanation:

Let the angle of elevation be $\theta$

$\therefore \tan \: \theta = \frac{height \: of \: mast}{height \: of \: shadow} \\ \\ \therefore \tan \: \theta = \frac{44}{14} \\ \\ \therefore \tan \: \theta = 3.14285714 \\ \\ \therefore \: \theta = {\tan}^{ - 1} (3.14285714) \\ \therefore \: \theta = 72.349875765 \degree \\ \\ \huge \red{ \boxed{\therefore \:\theta = 72.35 \degree}}$

Hence, angle of elevation of the sun is 72.35°.

Find the 10th term of the geometric sequence 8, -24, 72, ...

solniwko [45]

Answer:

-157464

Step-by-step explanation:

Geometric Sequence formula = ar^n-1

In the above formula,

a = the first term

r = common differnce

n = the term which we want to know

So, the first term is 8.

We can tell that these numbers have a common difference of -3.

We need to find the 10th term.

=> 8*(-3^10-1)

=>8*-3^9

=>8*-19683

=>-157464
