Answer:
∠A = ∠C = 60°
∠B = ∠D = 120°
Step-by-step explanation:
In quad. DPBQ, by angle sum property we have
∠PDQ + ∠DPB + ∠B + ∠BQD = 360°
60° + 90° + ∠B + 90° = 360°
∠B = 360° – 240°
Therefore, ∠B = 120°
But ∠B = ∠D = 120° opposite angles of parallelogram
As, AB || CD opposite sides of a parallelogram
∠B + ∠C = 180° sum of adjacent interior angles is 180°
120° + ∠C = 180°
∠C = 180° – 120° = 60°
Hence ∠A = ∠C = 60° Opposite angles of parallelogram are equal
We know that a square, by definition, has four congruent sides.
So, simply divide the perimeter by 4, and you will get the expression equivalent to each side: 12p+4/4
3p+1 is equal to one side of the square
Answer:
x=1.4
Step-by-step explanation:
Write the equation
Multiply both sides by x
Divide both sides by 4
