Customer Support. In the diagram below, AABC ARST. Determine and state the number of degrees in one interior angle of the 5. Which of the following statements are true? ABCD is a Rhombus in which BC = 25cm, AD = 24cm. Ab=cd 2x-7=x+y ---(1) 2x-x-y=7 or x-y=7 (3) bc=ad x+3y=2x-y-1 (2) x-2x+3y+y=-1 or -x+4y=-1 or x-4y=1 (4) solve these(3) &(4) two linear equations x-y =7 (3) x-4y =1 (4) Subtract(4)-(3) - + -----3y = 6 Or y=2 Substitute y=2 in (3) we get x-2=7 or x=9 Thus x=9 y=2 [ab 2*9-7=9+2 or 18-7 = 11 which are opp sides // &equal similarly bc &ad] The sum of the interior angles of a regular polygon is 540°. Which statement is not true? In the diagram below, it is given that AB CD and AB||CD. There's a point below point C in the diagram (where there's a right angle). Ex 8.2, 5 In a parallelogram ABCD, E and F are the mid-points of sides AB and CD respectively. In isosceles trapezoid ABCD, AB Il DC, and AD = BC. In parallelogram MATH, the degree measure of LT exceeds two times the degree measure of ZH by 30. (ii) diagonal BD bisects ∠B as well as ∠D. Find the value of y if AB = 2y — 7 and DC = 4y + 5, and EF=y+ 5 Areas Of Parallelograms And Triangles Parallelograms on the same base and between the same parallels are equal in area. CDA and CDB are right 4. Want a call from us give your mobile number below, For any content/service related issues please contact on this number, ABCD is a parallelogram.
