(-2,-5) is on the graph because -5-5=5*(-2)= -10=-10. therefore the equation is true

Two sides of a triangle have measures 3 ft and 6 ft. Also, these sides form a vertex whose angle measures 60 degrees. Calculate
Basile [38]

Answer:

A. The length of the third side is approximately 5 feet.

B. A = 88^{o}, B = 60^{o} and C = 32^{o}.

Step-by-step explanation:

Let the triangle be ABC. Given two sides and an included angle, let us apply the cosine rule to determine the third length.

A. Let side a = 6 feet and c = 3 feet, thus;

b^{2} = a^{2} + c^{2} - 2ac Cos B

  = 6^{2} + 3^{2} - 2(6 x 3) Cos 60^{o}

  = 36 + 9 - 36 x 0.5

  = 45 - 18

b^{2} = 27

b = \sqrt{27}

  = 5.1962

b  = 5.2 feet

b ≅ 5 feet

The length of the third side is approximately 5 feet.

B. Given that B = 60^{o}, then let us apply the Sine rule to determined the measure of A.

\frac{a}{SinA} = \frac{b}{SinB}

So that,

\frac{6}{Sin A} = \frac{5.2}{Sin60^{o} }

Sin A = \frac{0.886*6}{5.2}

Sin A = 0.99923

A = Sin^{-1} 0.99923

  = 87.75

A ≅ 88^{o}

Since the sum of angle in a triangle = 180^{o}.

Then,

A + B + C = 180^{o}

88^{o} + 60^{o} + C = 180^{o}

148^{o} + C = 180^{o}

C = 180^{o} - 148^{o}

     = 32^{o}

C = 32^{o}

Thus,

A = 88^{o}, B = 60^{o} and C = 32^{o}.

The percentage of the radioactive isotope left is 25.0000%.

<h3>What is the half life?</h3>

The half life of a radioactive isotope is the time that will elapse before only half of the number of original isotopes will remain.

Now;

We are told that;

Half life (t1/2) = 55 days

Time taken (t) =  115 days

Ratio of isotope remaining = N/No

Thus;

N/No = (1/2)^t/t1/2

N/No = (1/2)^115/55

N/No = (1/2)^2

N/No =1/4

Hence, the percentage = 1/4 * 100/1 = 25.0000%
