Answer:
The substance decays by 7.5% every year
Step-by-step explanation:
The inside angles of a triangle need to equal 180 degrees
in this triangle the lines NP and OP are identical so the 2 unknown angles would be equal
so the 2 unknown angles would be 180 - 112 = 68 / 2 = 34 each
angle N & O are 34 degrees
Answer:
![AB=6\sqrt{3}](https://tex.z-dn.net/?f=AB%3D6%5Csqrt%7B3%7D)
Step-by-step explanation:
![Given\ \angle A=30\textdegree\\\\AC=12\\\\\cos \theta=\frac{adjacent}{hypotenuse}\\\\\cos A=\frac{AB}{AC}\\\\\cos 30=\frac{AB}{12}\\\\\frac{\sqrt{3}}{2}=\frac{AB}{12}\\\\AB=6\sqrt{3}](https://tex.z-dn.net/?f=Given%5C%20%5Cangle%20A%3D30%5Ctextdegree%5C%5C%5C%5CAC%3D12%5C%5C%5C%5C%5Ccos%20%5Ctheta%3D%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D%5C%5C%5C%5C%5Ccos%20A%3D%5Cfrac%7BAB%7D%7BAC%7D%5C%5C%5C%5C%5Ccos%2030%3D%5Cfrac%7BAB%7D%7B12%7D%5C%5C%5C%5C%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D%3D%5Cfrac%7BAB%7D%7B12%7D%5C%5C%5C%5CAB%3D6%5Csqrt%7B3%7D)
Answer:
Step-by-step explanation:
