$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:Angle \:\: of \:\: elevation= 30°$

____________________________________

$\large \tt Solution \: :$

Let the angle of elevation be " x "

$\qquad \tt \rightarrow \: \cos(x) = \dfrac{9 \sqrt{3} }{18}$

$\qquad \tt \rightarrow \: \cos(x) = \dfrac{ \sqrt{3} }{2}$

$\qquad \tt \rightarrow \: x = \cos {}^{ - 1} \bigg( \cfrac{ \sqrt{3} }{2} \bigg )$

$\qquad \tt \rightarrow \: x = 30 \degree \: \: or \: \: \cfrac{ \pi}{6} \: \: rad$

Determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of t

VLD [36.1K]

We need to determine the term life insurance amount per thousand on a 22-year-old female for a 5-year policy given that the face value of the policy is $600,000 and the annual premium is $1332.

Since we are supposed to find the term life insurance amount per thousand, therefore, we will use the following formula:

$\text{Term life insurance amount}=\frac{\text{Annual premium}}{\text{Face value of insurance}}*1000$

Upon substituting the values of annual premium and face value of insurance, we get:

$\text{Term life insurance amount}=\frac{\text{1332}}{\text{600000}}*1000\\
\text{Term life insurance amount}=\$2.22$

Therefore, the required life insurance amount is $2.22.

What is the value of tan A?

Ronch [10]

For the given triangle, the tan of angle A equals $\frac{3}{4} = 0.75.$

Step-by-step explanation:

Step 1:

In the given triangle for angle A, the opposite side has a length of 6 cm, the adjacent side has a length of 8 cm while the hypotenuse of the triangle measures 10 cm. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

$tan A = \frac{oppositeside}{adjacent side}.$

Step 2:

The opposite side's length = 6 cm.

The adjacent side's length = 8 cm.

$tan A = \frac{oppositeside}{adjacent side} = \frac{6}{8} = \frac{3}{4} = 0.75.$
