I'm having a lot of trouble with this !

kayla wants to find the distance, ab, across a creek. she starts at point b and walks along the edge of the river 62 ft and marks point c. then she walks 93 ft further and marks point d. she turns 90° and walks until her final location and marks point e. point e, point a, and point c are collinear.

(a) can kayla conclude that ∆abc and ∆edc are similar? why or why not?

(b) suppose (de) ̅=125 ft. calculate the distance of (ab) ̅ to the nearest tenth of a foot. show your work. don’t forget to label your answer.

a ∆ABC and ∆EDC are similar

b. AB = 83.3 ft

Step-by-step explanation:

a.  We need to determine if  ∆ABC and ∆EDC are similar.

We know B = D = 90

We know C = C because they are vertical angles and vertical angles are equal

Therefore A = E because they are triangles, and if 2 angles in a triangle are equal the third angles must be equal.

∆ABC and ∆EDC are similar

b.  We know that because they are similar triangles

AB      BC

=

ED        DC

Substituting in

AB       62

=

125        93

Using cross products

93 AB = 62*125

93 AB = 7750

Divide by 93

AB = 7750/93

AB = 83.3333333333(repeating)

Rounding to the nearest tenth ft

AB = 83.3 ft

step-by-step explanation: yes

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
