Find the exact value of tan A in simplest radical form.
spin [16.1K]

Answer:

tan(A) = \frac{2\sqrt{15}}{11}

Step-by-step explanation:

Given:

Right ∆ABC

AB = 61

BC = 60

AC = 11

Required:

Value of tan A in radical form

SOLUTION:

tan(A) = \frac{opposite}{adjacent}

Opposite = 60

Adjacent = 11

tan(A) = \frac{60}{11}

tan(A) = \frac{\sqrt{4*15}}{11}

tan(A) = \frac{2\sqrt{15}}{11}

A house purchased for $216,500 gains 2% of its value every year. If this growth rate continues, in how many years will the house
NikAS [45]

Answer: 36 years

Step-by-step explanation:

You can use the Rule of 72 to calculate how long it might take the house to double in value.

The Rule of 72 works by dividing 72 by the interest rate as a whole number and the result will be a rough estimate of the time in years it will take for the investment to double in size:

= 72 / 2

= 36 years

The first side of a triangle is twice the length of the second side; the third side is 20 feet less than three times the second
oee [108]
Let the second side be x

then,
first side = twice the length of the second side
= 2x

third side = 20 feet less than three times the second side
3 (second side ) - 20
= 3 (2x) -20
= 6x - 20

perimete of a triangle = sum of all sides,

substitute the values we know,
and you'll be left with this equation

106 = x + 2x + 6x - 20
106+ 20 = 9x
126 = 9x
126/9 = x
14 = x

so,

measure of second side = x = 14 feet

measure of first side = 2x = 2 (14) = 28 feet

measure of thurd side = 6x - 20 = 6 (14)-20 = 84- 20 = 64 feet.
