Find x. Round your answer to the nearest tenth. <br><br> ______________
liubo4ka [24]

Answer:

Step-by-step expThis is the concept of trigonometry, the value of x will be calculated as follows;

sin theta=[opposite]/[hypotenuse]

theta=x

opposite=16 units

hypotenuse=21 units

thus;

sin x=16/21

hence;

x=arcsin(16/21)

x=49.63

x=50 (to the nearest degrees)

Which graph shows the solution to the following inequality. -5c+2&lt;27
bogdanovich [222]

Answer:

c > -5

Step-by-step explanation:

-5c + 2 < 27    

      - 2    - 2         Subtract 2 from both sides

-5c < 25               Divide both sides by -5 and flip the sign

c > -5

I graphed the inequality on the graph below.

The measures of the obtuse angles in the isosceles trapezoid are five more than four times the measures of the acute angles. Wri
emmainna [20.7K]

Answer:

a. i. x + y = 180  (1) and  x - 4y = 5   (2)

ii. The two acute angles are 35° each and the two obtuse angles are 145° each.

Step-by-step explanation:

a. The measures of the obtuse angles in the isosceles trapezoid are five more than four times the measures of the acute angles. Write and solve a system of equations to find the measures of all the angles.

i. Write a system of equations to find the measures of all the angles.

Let x be the obtuse angles and y be the acute angles.

Since we have two obtuse angles at the top of the isosceles trapezoid and two acute angles at the bottom of the isosceles trapezoid, and also, since the sum of angles in a quadrilateral is 360, we have

2x + 2y = 360

x + y = 180  (1)

Its is also given that the measures of the obtuse angles in the isosceles trapezoid are five more than four times the measures of the acute angles.

So, x = 4y + 5   (2)

x - 4y = 5   (2)

So, our system of equations are

x + y = 180  (1) and  x - 4y = 5   (2)

ii. Solve a system of equations to find the measures of all the angles.

Since

x + y = 180  (1) and  x - 4y = 5   (2)

Subtracting (2) from (1), we have

x + y = 180  (1)

-

x - 4y = 5   (2)

5y = 175

dividing both sides by 5, we have

y = 175/5

y = 35°

From (1), x = 180° - y = 180° - 35° = 145°

So, the two acute angles are 35° each and the two obtuse angles are 145° each.

PLEASE HELP!!
I am Lyosha [343]

Answer:

50 stuffed animals and 22 mystery boxes.

Step-by-step explanation:

Firstly, we assign variables.

Let the number of stuffed animals be x and the number of mystery boxes is y

The probability of selecting a stuffed animal is x/72 while the probability is selecting a mystery box is y/72

Now, since the total probability can be 1:

This means that

x/72 + y/72 = 1 •••••••(i)
