The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93

Answer:
370 m²
Step-by-step explanation:
Front and back
a = 2(11 * 6)
a = 132 m²
Right and left sides
a = 2(7 * 6)
a = 84 m²
Top and bottom
a = 2(11 * 7)
a = 154 m²
______________________
total
a = 132 + 84 + 154
a = 370 m²
