c 230 C A b=72ft The above triangle is common and angles of constructed using the notation for representation of sides according to which represented in capital letters with opposite to them in small letters. a are angles sides * Applying the angle sum sule in AABC. A+B+C =180° z) B = 180°- A-C >> B= 180°-23°-90° 2) B-670 In OABC, 2009 tan 23° = berpendicular base BC - - a AC a b 72 =) a= 72 tan 23° feet =) ař 30.5622 ~ 31 feet - C 1 Cos 23. = base AC b 72 hypotenuse AB =) c= 72 ã 78.21795 –78 feet cos23° 6° 3 : 67 ; a=31 feet ; C=78 feet
