Answer:
∠ BAC = 80°
Step-by-step explanation:
The sum of the interior angles of quadrilateral ACDB = 360°
DB and DC are tangents to the circle, thus
∠ DBA = ∠ ACD = 90° ( angle between tangent/ circle at point of contact )
Thus
∠ BAC + 90° + 90° + 100° = 360°
∠ BAC + 280° = 360° ( subtract 280° from both sides )
∠ BAC = 80°

Answer:
35m
Step-by-step explanation:
120m
Rojo: 1/8 . 120m --- el resto son 7/8 . 120m
Azul: 1/3 . 7/8 . 120m = 7/24 . 120m = 7/2 . 10m = 70m / 2 = 35m
Divide both sides by
- note that this means we can't have
:


Then the left side reduces to the derivative of a product,
![\dfrac{\mathrm d}{\mathrm dx}\left[\dfrac1xy\right]=\sin x](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Cleft%5B%5Cdfrac1xy%5Cright%5D%3D%5Csin%20x)


This solution is continuous everywhere, but accounting for the singular point
, the largest interval over which it is defined would be
