In circle A, ZBAE = ZDAE.
Levart [38]

Incomplete question the complete question with the diagram is given below.

Answer:

The Correct option is second one 17 units.

Therefore the Length of BE is 17 units.

Step-by-step explanation:

Given:

∠BAE = ∠DAE

BE = 3x - 24

DE = x + 10

To Find :

Length of BE = ?

Solution:

∠BAE = ∠DAE        .........Given:

As Chords that subtend congruent angles are congruent. That is equal angles subtends equal chords.

So , the chord BE and DE are equal

Substituting the values we get

BE=DE\\3x-24=x+10\\2x=34\\\\x=\dfrac{34}{2}=17\\\\x=17\ units

Therefore the Length of BE is 17 units.

1. The number a is 4/5 of the number b. What part of number a is number b?
alexdok [17]
Writing some equations out might help!

1) You know that a is 4/5 of b. This can be written as:a =  \frac{4}{5} b.
To find what b is equal to, multiply both sides by 5/4: \frac{5}{4}a = b.
A is 5/4 B. 

2) You know that a is 1/5 smaller than b. This can be written as: a = b - \frac{1}{5}.
To find b, just add 1/5 to both sides: a +  \frac{1}{5} = b.
B is 1/5 bigger than a.

77julia77 [94]

Answer:

she goes 60mi for every hour for 2 hrs.

then she stops for 30 min which means the line = flat.

After that she drives at 30mi for every hour, but because she drives for 1 hour only, that’s 30 mi, so the line stops in the middle of the square (aka 30 mi after the stop time she took for her flat tire).
