8. In AABC, LA is a right angle and mzB = 45°. Find BC.

Margaret [11]

Answer:

BC = 11 $\sqrt{2}$

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$ , then

sin 45° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{BC}$ = $\frac{11}{BC}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

BC = 11 $\sqrt{2}$

Please help quickly! <br><br> What is the measure of Arc CB. How did you determine this?

S_A_V [24]

Answer:

As shown in picture,

Angle CDF = Angle BDE = 54 deg (pair of opposite angles)

Angle CDB = 180 - CDF = 180 - 54 = 126 deg (BF is a diameter).

=> Arc CB = Angle CDB = 126 deg (property of angle on circle)

Hope this helps!
