31. In the given figure o is the center of circle. A,the points on the circle. AOC-110, FindC and22m and32 The me |
|
Answer» Angle subtended by an arc is twice the angle subtended by it on the circumference in the alternate segment. Here arc ABC makes ∠ AOC = 110° at the center of the circle and ∠ ADC on the circumference of the circle. ∴ ∠ AOC = 2∠ ACD ⇒ ∠ ACD = ½ (∠AOC) ⇒ = ½ × 110° [∠ AOC = 110°] ⇒ ∠ ACD = 55° The opposite angles of a cyclic quadrilateral are supplementary. ABCD is a cyclic quadrilateral and thus, ∠ ACD + ∠ ABC = 180° = 180° – 55° [∵ ∠ ADC = 55°] = 125° ∴ ∠ ABC = 125° ∴ ∠ ACD = 55° and ∠ ABC = 125° |

what is angle name them |
|
Answer» The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet. Two lines that form a rightangleare said to be normal, orthogonal, or perpendicular. Angleslarger than a rightangleand smaller than a straightangle(between 90° and 180°) are called obtuseangles("obtuse" meaning "blunt"). Anangleequal to 12 turn (180° or π radians)is calleda straightangle. |

3x+2y=52x+3y=6 |
|
Answer» 3x+ 2y = 5 2x + 3y = 6 multiply eq. (1) with 3 and eq. (2) with (-2) and add both the equations 9x + 6y - 4x - 6y = 15 - 12 5x = 3 so x=3/5 9/5 + 2y = 5 so 2y = 5-9/5 = 16/5 so y = 8/5 |
