Answer:

X=23

Step-by-step explanation:

You should know that a triangle =180 degrees

Add all your angles together and =180

66+2x+3+3x-4=180

add similar terms

5x+65=180

Move your 65 to the other side

5x=115

x=23

(Optional)

to check if your answer is right substitute your x and add all angles together you should get 180 degrees.

An average mosquito found in the environment gives of 12.6 disintigrations per minute per gram of carbon. a preserved mosquito f
lord [1]

From the half life equation, the remaining fraction (\frac{1}{2} )^{\frac{t}{T} }

where t = total time elapsed and T = Half life

Now,  it is given that, T=5730

And remaining fraction is=\frac{1.575}{12.6}

So, substituting these values in the above equation,

\frac{1.575}{12.6}=(\frac{1}{2} )^{\frac{t}{5730} }\\0.125=0.5^{\frac{t}{5730}

Taking log both sides,

log(0.125)=log(0.5)*\frac{t}{5730}

Solving, we obtain that,

t=17190 years

Area = (3.14)(12)²

Area = (3.14)(144)

Area = 452.16 in²
