In the given parallelogram, BE and CE are angle bisectors. If m∠A = 70°, find m∠BEC.

Iteru [2.4K]

Answer:

∠BEC=90°

Step-by-step explanation:

∠A=∠BCD and ∠ABC=∠D because opposite angles in a parallelogram are equal.

∠A=∠BCD=70

All angles in a quadrilateral add to 360:

∠A+∠ABC+∠BCD+∠D=360

∠ABC+∠D=360-140=220

∠ABC=∠D=110

Since ∠ABC=∠ABE+∠EBC, and ∠ABE=∠EBC (because BE is an angle bisector), ∠EBC=55.

Since ∠BCD=∠BCE+∠ECD, and ∠BCE=∠ECD (because CE is angle bisector), ∠BCE=35.

All angles in a triangle add to 180:

∠BCE+∠EBC+∠BEC=180

35+55+∠BEC=180

∠BEC=180-90

∠BEC=90°

A x 4 = E

lana [24]

A * 4 = E........A = E / 4
B / 4 = E........B = 4E
C + 4 = E......C = E - 4
D - 4 = E.......D = E + 4

A + B + C + D = 100
(E/4) + (4E) + (E - 4) + (E + 4) = 100
E/4 + 6E = 100 ....multiply by 4
E + 24E = 400
25E = 400
E = 400/25
E = 16 <===

What is the value of e^3x+6=8

Natasha2012 [34]

Hello there!

<u><em>Answer: ⇒⇒ $x=\frac{2}{e^3}$ </em></u>

___________________________________________________

Step-by-step explanation:

First you had to subtract by 6 from both sides of equation.

$e^3x+6-6=8-6$

Simplify.

$e^3x=2$

Then you divide by e³ from both sides of equation.

$\frac{e^3x}{e^3}=\frac{2}{e^3}$

Simplify it should be the correct answer.

$x=\frac{2}{e^3}$

Answer:

$95,183.04

Step-by-step explanation:

$A = P(1 + \frac{r}{n} )^{nt}$

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

(i used a calculator but theres the formula^^ T-T)
