The area of the trapezoid formula can be solved for the variable h as,

h = 2A / (b1 + b2)

Given the formula to find the area of the trapezoid.

A = 1/2 (b1 + b2) h

Here A is the area, h is the height and b1 and b2 are the bases of the trapezoid.

We have to get an equation for formula in h.

That is, we need to isolate h alone on one side and the other terms and variables on other side.

Multiplying whole equation with 2,

2A = (b1 + b2) h

Dividing whole by (b1 + b2),

h = 2A / (b1 + b2)

Hence the required equation is h = 2A / (b1 + b2).

Explanation:

LA stands for Leg Angle. More specifically, the angle is an acute angle. This theorem only works for right triangles. We see that ED = LK which is one pair of congruent leg segments. So that takes care of the L part of LA. However, we don't know anything about the acute angles. We don't know if angle E = angle L, or if angle F = angle M, or something along those lines. We need angle markers to tell us or not.

In short, we only have half the info needed for LA, so we must cross choice A off the list.

----------------

HA stands for hypotenuse angle, or hypotenuse acute angle, and this rule only applies for right triangles. We don't know anything about the hypotenuse lengths if they are the same or not.

Similar to choice A, we don't know anything about the acute angles either.

Those two facts mean we must cross off choice B.

----------------

AAS stands for Angle Angle Side. The order is important because the side is not between the angles. The diagram only shows one pair of angles that are congruent to one another. That pair being the 90 degree angles indicated with the square marker. We don't have another pair of angles, so we cannot use AAS.

Cross choice C off the list.

-----------------

We can use SAS because we have two pairs of congruent sides and one pair of congruent angles.

The congruent sides are

That takes care of the two "S"s of "SAS". The "A" would be those two right angles which are congruent to one another. The angles are between the congruent sides which is important. Recall that SSA is not a valid congruence theorem.

So that's why choice D is the only answer.

-----------------

Side note: We could use the LL theorem, where L stands for leg, since we are given two pairs of congruent legs for each triangle. Like LA and HA, this only applies to right triangles. LL is a special case of SAS. However, LL isn't listed so we'll just be sticking with SAS as the only answer.

Answer: The mode is greater than 7.

Step-by-step explanation:

The time in minutes are given as 9, 15, 5, 7, 9, 12, 11, 4. We can arrange them in ascending order and this will be:

= 4, 5, 7, 9, 9, 11, 12, 15

Mean = (4 + 5 + 7 + 9 + 9 + 11 + 12 + 15) / 8 = 9

Median = 9+9/2 = 18/2 = 9

Mode = 9

Range = 15 - 4 = 11

Therefore, the true statement are:

D. The mode is greater than 7.

First find height.

Use trigonometric ratios:

sin85 = h/9.5

h = 9.5sin85 = 9.46 yd

Use the following formula:

A = [tex]\frac{1}{2}[/tex]bh

A = [tex]\frac{1}{2}[/tex] (23)(9.46)

A = 108.83 yd²

we have y≥2x-2 ------> inequality A

The inequality A is the solid red line in the graph the solution of the inequality A is the shaded area above the solid red line x+4y≥?------> inequality B The inequality B is the solid blue line in the graph the solution of the inequality B is the shaded area above the solid blue line we know that the point (0,-3) lie on the line of the inequality B. substitute the values of x and y in the equation of the line

x+4y=c

0+4*(-3)=c

c=-12

so the answer is -12

The system of linear inequalities is:

y > 2x – 2 and x + 4y > -12.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥  

We have,

When x = 0, y = 2(0) – 2 = -2.

So the point (0, -2) is on the line.

When x = 2, y = 2(2) – 2 = 2.

So point (2, 2) is on the line.

Plotting these two points and drawing a line through them gives us the graph of y = 2x – 2.

Next, let's graph x + 4y = -12 by solving for y:

x + 4y = -12

4y = -x - 12

y = (-1/4)x - 3

Again, we can plot two points on the line.

When x = 0, y = -3, giving us the point (0, -3).

When x = -4, y = -2, giving us the point (-4, -2).

Plotting these points and drawing a line through them gives us the graph of x + 4y = -12.

Thus,

The solution to the system of inequalities is the shaded region where the two graphs intersect and y > 2x – 2.

This region is shown in the attached image.

Answer:

A = 65deg

B = 78deg

Step-by-step explanation:

It's a triangle, so we know that the sum of angles is 180deg

x + (2x - 9) + (2x + 4) = 180

5x - 5 = 180

5x = 185

x = 37

Measure of angle A = (2*37 - 9)deg = 65deg

Measure of angle B = (2*37 + 4)deg = 78deg

Answer:

Step-by-step explanation:

8x + 38 = -3(-6 - 4x)

8x + 38 = -3(-4x - 6)

8x + 38 = -3 (-4x - 6)

8x + 38 = 12x + 18

8x +38 = 12x + 18

8x + 38 - 38 = 12x + 18 - 38

8x + 38 - 38 = 12x + 18 - 38

8x = 12x + 18 - 38

8x= 12x - 20

8x = 12x - 20

8x - 12x = 12x - 20 - 12x

8x - 12x = 12x - 20 - 12x

-4x = 12x - 20 -12x

-4x = 12x - 20 -12x

-4x = - 20

-4x = -20
