Answer:
B. 99 square units
Step-by-step explanation:
The <em>parallelogram</em> is a quadrilateral where the opposite sides are parallel to each other. This geometric figure constitutes, therefore, a polygon that consists of 4 sides where there are two cases of parallel sides.
To calculate the area of a parallelogram, you must know the length of the height relative to one of its sides.
Let the base be the side x and the height (h) relative to the base. The area of the parallelogram is the product of the base and the height.
Where:
a is the area in square units.
x is the base in units.
h is the height in units.
Solving:
With x = 11 units and h = 9 units
Answer:
X AND Z
Step-by-step explanation:
Y cant be right since it takes up half the ear while the other dont
The answer is C.
Because when dealing with a contemplative you state the statement but first you flip the words. Then you change it from saying:
Example-
I can
To I can't
Hope that helped you understand it more
The ideal mechanical advantage of a slope is given by the ratio between the output load, which is simply the weight of the object (), and the input force applied to move the object along the slope:
The energy conservation law states that the potential energy of the object when it reaches the final height h is equal to the work done to move the object along the distance of the slope , i.e.
From this we find
Therefore, we can substitute this into the formula of the ideal mechanical advantage and calculate its value:

Answer:
m<1 = 60°
m<2 = 30°
m<3 = 90°
Step-by-step explanation:
Recall some properties of Rectangle. Thus:
The four angles of a rectangle are right angles = 90° each.
Opposite sides of a rectangle are also parallel to each other.
With the knowledge of these, we can solve for angles 1, 2, and 3.
Thus:
m<1 = 60° (alternate interior angles are congruent)
m<2 + m<1 = 90° (complementary angles)
m<2 + 60° = 90° (substitution)
m<2 = 30° (substraction property of equality)
m<3 = 90° (angle of a rectangle)
