so the tank tops are 70% off, meaning, 100% - 70% = 30%, the price you pay for one is just 30% of the regular price, if we put that in decimal that'd be (30/100), or just 0.3.
since the price of a tank top is "t", then for 2 is 2t, and the discounted price will just be 30% of "t" so (0.3)2t.
we now the t-shirts are each one 12 bucks discounted already, so for 3 of those will just be (3)(12).
the jeans are half off, namely 50% off, if we put that in decimals, that'd be (50/100) or just 0.5.
we know the regular price of the jeans is "j", so the discounted price will just be (0.5)j, and for just one well, (0.5)(1)j or just 0.5j.
A convex figure with three sides is triangle. The sum of the measures of all interior angles of the triangle is 180°.
Let
be interior angles of this triangle. Then
![\alpha+\beta+\gamma=180^{\circ}.](https://tex.z-dn.net/?f=%5Calpha%2B%5Cbeta%2B%5Cgamma%3D180%5E%7B%5Ccirc%7D.)
Find exterior angles of this triangle:
1.
is exterior angle adjacent to the interior angle ![\alpha.](https://tex.z-dn.net/?f=%5Calpha.)
2.
is exterior angle adjacent to the interior angle ![\beta.](https://tex.z-dn.net/?f=%5Cbeta.)
3.
is exterior angle adjacent to the interior angle ![\gamma.](https://tex.z-dn.net/?f=%5Cgamma.)
The sum of the measures of all exterior angles is
![180^{\circ}-\alpha+180^{\circ}-\beta+180^{\circ}-\gamma=540^{\circ}-(\alpha+\beta+\gamma)=540^{\circ}-180^{\circ}=360^{\circ}.](https://tex.z-dn.net/?f=180%5E%7B%5Ccirc%7D-%5Calpha%2B180%5E%7B%5Ccirc%7D-%5Cbeta%2B180%5E%7B%5Ccirc%7D-%5Cgamma%3D540%5E%7B%5Ccirc%7D-%28%5Calpha%2B%5Cbeta%2B%5Cgamma%29%3D540%5E%7B%5Ccirc%7D-180%5E%7B%5Ccirc%7D%3D360%5E%7B%5Ccirc%7D.)
