Answer:
172 cm².
Step-by-step explanation:
Total surface area = 56 + 16 +56 + 16 + 14 + 14
X = 3
Y = 4/3
You solve the problem by substitution method
To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.
Apart from each other.
This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.
So the expression would be
2x - 9 + 27 = 90
2x + 18 = 90
2x = 90 - 18
2x = 72
X = 72/2 = 36 degrees.
For the second question since w and v are parallel that means the angles are equal to each other
Thus make the expressions and value equal to each other and solve for x
3x + 60 = 120
3x = 60
X = 20 degrees.
