BCD is a straight line and because ACD = 115+x, then consequently, ACB = 180-(115+x) = 65-x Now using the sine rule: sin(65-x)/AB = sin(ABC)/AC but AB = AC so sin(65-x) = sin(ABC) hence ABC = 65-x So then BAC = 180 - 2(65-x) = 50+2x.

Show all your reasoning. Answers (2) Tallon 26 January, 14:59. M is the midpoint of OA. 0. AB = 75 cm Step-by-step explanation: Since ABC is a straight line, then AB + BC = AC let BC be x then AB = 5x and summing gives 5x + x = 90 6x = 90 (divide both sides by 6) x = 15 Thus AB = 5x = 5 * 15 = 75 cm. 21. In geometry, the notion of line or straight line was introduced by ancient mathematicians to represent straight objects (i.e., having no curvature) with negligible width and depth.

The value of x , is . A straight line, L, is perpendicular to the line with equation y = 1 – 3x. Question 1: If C be the centroid of the triangle having vertices (3,−1), (1,3) and (2, 4).Let P be the point of intersection of the lines x + 3y − 1 = 0 and 3x − y + 1 = 0, then the line passing through the points C and P also passes through the point: thanks. The intercepts on the straight line y = m x by the lines y = 2 and y = 6 is less than 5, then m belongs to. LEARNING APP; ANSWR; CODR; XPLOR; SCHOOL OS; STAR; answr. BCD is a triangle. ABC is a straight Line with AB = BC = 0.60 nm. AC=75. View solution. Abc is a straight line. Answer: AB = 60, BC = 15 Step-by-step explanation: AB is 4 times bigger than BC ⇒ AB = 4BC Use the Segment Addition Property: AB + BC = AC and substitution (replace AB with 4BC) and (AC with 75) to solve for BC 4BC + BC = 75 5BC = 75 BC = 15 AB = 4BC = 4 (15) = 60. DA is a tangent to the circle. The length of AB is four times bigger than BC. Which describes the relationship between 21 and Z2? B is the midpoint of AC.
