Answer:

∠ ABC = 81° , ∠ FEC = 90°

Step-by-step explanation:

Since AB ≅ BC then Δ ABC is isosceles.

The median BE is therefore

The angle bisector of ∠ ABC and

BE bisects AC at right angles.

Thus

∠ ABE = ∠ CBE = 40° 30' , then

∠ ABC = 2 × 40° 30' = 81°

Since BE is perpendicular to AC then

∠ FEC = 90°

Find two consecutive even integers whose sum is 14
bagirrra123 [75]
Let x = small number
Let y = large number 
Because they are consecutive even numbers,they must have a difference of 2:
y-x=2
y=2+x

Eqn 1: x+(2+x)=14

Eqn 2: x(2+x)=48

2x+2=14
2x=12
x=6

This means y must be 8 

so your two numbers are 6 and 8

Answer:

  • y = -16
  • x = 10

Step-by-step explanation:

The direct proportion equation is ...

  y = kx

where k is the constant of proportionality. Here, you're told k=-2, so the equation is ...

  y = -2x

For x=8, the value of y is ...

  y = -2(8) = -16 . . . . . do the multiplication

For y = -20, the value of x is ...

  -20 = -2x

  10 = x . . . . . . . . . divide both sides by -2
