Answer:

The answer is ∠7 ≅ ∠4 is not true

Step-by-step explanation:

∵ l // n

∴ ∠2 = ∠6 ⇒ corresponding angles

∵ ∠6 = ∠8 ⇒ vertically opposite angles

∴ ∠8 = ∠2

∵ ∠5 = ∠3 ⇒ alternate angles

∵ ∠4 + ∠5 = 180° ⇒ interior supplementary angles

∵ ∠7 = ∠5 ⇒ vertically opposite angles

∴ ∠4 + ∠7 = 180°

∴ ∠7 ≠ ∠4

<h2>Answer:</h2>

<u>Angle </u><u><7 and < 4 </u><u>are not equal</u>

<h2>Step-by-step explanation:</h2>

As we see in the figure angles are formed by a transversal intersecting two parallel lines. If two parallel lines are cut by a transversal, then the alternate interior angles formed are congruent . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles. But if we take two angles which are neither supplementary not complementary or any other suitable rule then they are not equal just as angle 4 and angle 7, they do not lie under any rule.

A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. Is the r
cluponka [151]

Answer:

  not enough information

Step-by-step explanation:

Dividing altitude by hours, we find the ratios to be 400/2 = 200 ft/h and 700/6 = 116 2/3 ft/h.

These are not the same ratio, so altitude is not proportional to time.

___

However, that's not what the question asks. It ask about rate of change. We only have enough information to determine the rate of change between hour 2 and hour 6 is 300 ft in 4 hours, or 75 ft/hour. Since we don't have any other rate of change information, we cannot determine if the rate of change is proportional to anything.

_____

<em>Comment on the question</em>

We suspect the question is simply worded poorly, and that we're supposed to determine if altitude is proportional to hours. (It is not). If that is actually the question, "rate of change" needs to be left out of the question.

oksano4ka [1.4K]

Answer:

instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals

ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min

A square has a perimeter of 12 cm. do you know its area
Anvisha [2.4K]

Answer:

9 cm^2

Step-by-step explanation:

If the perimeter of the square is 12 cm, then the length of ONE side is (1/4) of that, or 3 cm.

The area of this square is A = s^2, where s is the length of one side.

Here we have A = (3 cm)^2 = 9 cm^2.
