Find the measures of x and y

Answers

Answer:

x = 65°y = 25°

Step-by-step explanation:

We can clearly see that 90 = x + 25. Let's solve for x.

=> 90 = x + 25=> x = 65°

Since we found x, we can find y by substituting x in the equation 90 = x + y

=> 90 = x + y=> 90 = 65 + y=> y = 25°

Conclusion:

Therefore, we found that:

x = 65°y = 25°

Area of shaded part = 72sq.cm

But 72 = 3h - 4 + 6h - 4 + 4h

completing the square: x^2+2x-7=8x

Answers

Answer: x = 7, x = -1

Step-by-step explanation: Move the term to the left side

x^2 + 2x - 7 = 8x

x^2 + 2x - 7 - 8x = 0

Combine like terms

x^2 + 2x - 7 - 8x = 0

x^2 - 6x - 7 = 0

x^2 - 6x - 7 = 0

Given the figure below, which statement correctly completes the following? ABE and HCD are what type of angles

Answers

Angles are classified based on their measures.

Classification of angles

The following are the classification of angles

Acute AnglesRight AnglesObtuse AnglesStraight linesReflex Angles

The smallest angle is 0 degrees and the largest is 360 degrees.

When the measure of an angle is less than 90 degrees, such angle is an acute angle

When the measure of an angle is exactly 90 degrees, such angle is a right angle

Angles greater than 90 degrees, but less than 180 degree are obtuse angles, while angles that measure exactly 180 degrees are straight lines.

The last type of angle is the reflex angle, and it has a measure between 180 degrees and 360 degrees (exclusive)

Step-by-step explanation:

The Hi.nge theorem says that the side opposite the angle between two pairs of congruent sides is longer if the angle is larger. This theorem is applicable to problems 5-8, and your application is correct.

__

9) The Hi.nge theorem does not apply. The marked angles are not between the congruent sides. There is no necessary relation between the marked angles and the angles that are between the congruent sides, so no conclusion can be drawn regarding the relative lengths of AB and CD.

What is square?

A square is a quadrilateral with all sides congruent to one another.

Given is to find the measure of angles given in the question.

We can write the measure of angles as -

m ∠EFG = 90°

m ∠EFG = 45°

m ∠FEG = 45°

m ∠DHG = 45°

Therefore, the measure of the given angles are -

m ∠EFG = 90°

Sarah works for 8 minutes and for every 8 minutes she gains 23 coins everytime she works and she is saving for 2,000 coins in total. How many hours will it take Sarah to get 2,000 coins?

Answers

Answer:

11.59 hours  {Basically 12 hours]

Step-by-step explanation:

Sarah's coin rate is 23 coins/8 minutes, or 2.875 coins/minute

Rate * Time(X) = Coins

(2.875 coins/min)*(X) = 2000 coins

X = (2000 coins)/(2.875 coins/min)

X =  695.65 minutes

(695.65 minutes)*(1 hour/60minutes) = 11.59 hours
