Angle C is inscribed in circle O. AB is a diameter of circle O. What is the measure of ZB?

Soloha48 [4]

Answer:

∠ B = 19°

Step-by-step explanation:

note ∠ C = 90° ( angle in a semi- circle )

The sum of the 3 angles in the triangle = 180°, thus

∠ B = 180° - (90 + 71)° = 180° - 161° = 19°

$\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^{-n} \qquad \qquad a^n\implies \cfrac{1}{a^{-n}} \\\\ -------------------------------\\\\ 8^{-2}\cdot \cfrac{3^0-8^{-3}}{4^{-5}}\implies 8^{-2}\cdot \cfrac{1-\frac{1}{8^3}}{\frac{1}{4^5}}\implies 8^{-2}\cdot \cfrac{1-\frac{1}{(2^3)^3}}{\frac{1}{(2^2)^5}}$

$\bf 8^{-2}\cdot \cfrac{\quad \frac{512-1}{2^9}\quad }{\frac{1}{2^{10}}}\implies (2^3)^{-2}\cdot \cfrac{\quad \frac{511}{2^9}\quad }{\frac{1}{2^{10}}}\implies 2^{-6}\cdot \cfrac{511}{2^9}\cdot \cfrac{2^{10}}{1} \\\\\\ 2^{-6}\cdot \cfrac{511\cdot 2^{10}}{2^9}\implies 2^{-6}\cdot 511\cdot 2^{10}\cdot 2^{-9}\implies 2^{-6}\cdot 511\cdot 2^{10-9} \\\\\\ 2^{-6}\cdot 511\cdot 2\implies 511\cdot 2^{-6}\cdot 2\implies 511\cdot 2^{-6+1}\implies 511\cdot 2^{-5} \\\\\\ 511\cdot \cfrac{1}{2^5}\implies \cfrac{511}{32}$

7nadin3 [17]

Answer:

912.9 miles total

Step-by-step explanation:

75.4 miles biking x 8 times = 603.2 miles in biking

22.4 miles running x 3 days = 67.2 miles in running

27.5 miles running x 5 days = 137.5 miles running (2nd)

15 miles swimming x 7 days = 105 miles swimming

603.2+67.2+137.5+105 =

912.9 miles total
