Answer:
x^2 - 49= (x+7) (x -7)
Step-by-step explanation:
Since AB = CD the trapezoid is isosceles, which means that ∡A = ∡D
Therefore also ∡2 = ∡3 (they are half of the congruent angles)
For the properties of parallel lines (BD and AD) crossed by a transversal (BD) we have ∡3 = ∡CBD.
Now consider triangles AOD and BCD:
∡OAD (2) = ∡ADO (3) = ∡CBD (3) = ∡CDB (4)
T<span>he sum of the angles of a triangle must be 180°, t</span>herefore:
∡AOD = 180 - ∡2 - ∡3
∡BCD = 180 - ∡3 - ∡4
∡AOD = ∡BCD because their measure is the difference of congruent angles.
Answer:
47-Step-by-step explanation:
X=121 because they are vertical angles
48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3
