Angle BEC is the unmarked angle in the middle of the figure. Its value is the difference between straight angle AED (180°) and the two marked angles, 57° and 33°. That difference is ...

... 180° - 57° -33° = 90°

∠BEC is a right angle.

Answer:

Right angle

Step-by-step explanation:

We are given that

Angle AEB=57^{\circ}

Angle CED=33^{\circ}

We have to find  the classification of angle BEC

We know linear sum =180^{\circ]

Angle AEB +Angle BEC+Angle CED=180

Substitute the values then we get

57+33+\angle BEC=180^{\circ}

90+\angle BEC=180

\angle BEC=180-90

\angle BEC=90^{\circ}

Hence, the angle BEC is right angle

What are the remaining angle measures if the figure is to be a parallelogram?
goldfiish [28.3K]

The correct answer is  

m∠B ==101°,

m∠C =79°,

m∠D=101°

Step-by-step explanation:

  • As we know that, it is a parallelogram opposite angels are congruent
  • Therefore,  m∠A = m∠C and m∠B =m∠B
  • As we know that, If side a=79 then side c must also be equal to 79
  • When we consider all the angles and add them it must be equal to 360°
  • When we add 79+79 = 158°, which mean a=c= 158°
  • By subtracting all the sides of parallelogram which is 360- 158= 202°
  • If we divide it by 2 then we will get the value of the other side of the angle which is  b and d.
  • Dividing 202 by 2
  • \frac{202}{2} = 101°
  • Therefore, the value of b=d=101°
  • A Parallelogram is a flat shape with an opposite sides parallel and they are equal in length.
  • A parallelogram has four sides, and the opposite sides are parallel and they don't intersect.

For the graphed function f(x) = -(5)* - 3 + 2, calculate the average rate of change from x = 3 to x = 4.
Ilia_Sergeevich [38]

Answer:

-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is \frac{f(b)-f(a)}{b-a}

The given function is f(x)=-5^{x-3}+2.

f(4)=-5^{4-3}+2=-3.

f(4)=-5^{3-3}+2=1.

The average rate of change from x=3 to x=4 is given by:

\frac{f(4)-f(3)}{4-3}

\frac{-3-1}{4-3}=-4

a manufacturer ships its product in boxes with edges 4inches. if 12 boxes Are put in a carton and completely fill the carton, wh
Soloha48 [4]
The volume of a box is equal to the product its width, length and height
V = whl
Since all of the sides are 4 inches, we end up with
V= 4*4*4
Simplify to V = 16*4 = 64.
If the volume of one box is 64:
V = 64
The volume of 12 boxes is 64 * 12.
12V = 768
Since the volume of 12 boxes is the same as the volume of the carton, the volume of the carton must be 768 cubic inches.
