Answer:
x = 63°
y = 45°
z = 72°
Step-by-step explanation:
<u>Points to remember</u>
1). Opposite angles of a parallelogram are equal
2). Adjacent angles of a parallelogram are supplementary
3). Sum of angles of a triangle is 180°
<u>To find the measures of given angles</u>
ABCD is parallelogram.
m<C = m<C = x = 63°
Consider triangle ABD
m<A + m< B + m<D = 180
x + 72 + y = 180
y = 180 - ( 72 + x) = 180 - 135
y = 45°
Also y + z + m<C = 180
45 + z + 63 = 180
z = 180 - 108
z = 72°
Answer:
Step-by-step explanation:
Since both are perfect squares use the difference of squares formula 
with a = 
and b = 3
=
La raíz cuadrada de 49 es 7. Una raíz cuadrada es cuando puedes tomar un número y multiplicarlo por sí mismo para obtener un número entero. Por ejemplo, 3x3 = 9 4x4 = 16 5x5 = 25 6x6 = 36 7x7 = 49 y así sucesivamente!
