Step-by-step explanation:

let \: angle \: be \:  \alpha  \\  \tan( \alpha )  =  \frac{p}{b}  \\  \tan(69.9)  = \frac{9.7}{bc}  \\ bc =  \frac{9.7}{2.73}  \\ bc = 3.55 \\ by \: using \: pythagorean \: theorem \\ ab =  \sqrt{ {9.7}^{2} }  +  {2.73}^{2}  \\ ab = 10.07

How do I do this? Please help
Murljashka [212]
X is 90 degrees. If AB is the diameter, then it passes through the centre. X is 90 degrees because the angle in a semicircle is always a right angle.

PLZZ HELP!!!! ASAP PLZ!!!!<br> XTRA POINTS!!!
schepotkina [342]

Answer:

38.1 cm²

Step-by-step explanation:

area of full circle = π6² = 113.04 cm²

area of 150° segment = (150/360)(113.04) = 47.1 cm²

triangle base = sin 75° x 6 x 2 = 11.59

triangle height = cos 75° x 6 = 1.553

area of triangle = 1/2(11.59)(1.553) = 9 cm²

150° segment - triangle = 47.1 - 9 = 38.1 cm²
