100 POINTS Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity.

In the given triangle ABC, angle A is 90° and segment AD is perpendicular to segment BC.

The figure shows triangle ABC with right angle at A and segment AD. Point D is on side BC.

Part A: Identify a pair of similar triangles. (2 points)

Part B: Explain how you know the triangles from Part A are similar. (4 points)

Part C: If DB = 9 and DC = 4, find the length of segment DA. Show your work. (4 points)

read explanation

Step-by-step explanation:

part A: ABD is similar to ACD

part B: with A being 90 degrees and it being split in 2 ABC and ACD are both 90 degrees leaving them to be congruent

part C: this is where i got stuck but i got 9 units which is trigonometry or something but i’ll give the info i have!

D is 90 degrees so is angle A

ABD is 45 degrees

90+45+45 makes 180

DB and angle A is 45 degrees

i’m sorry i couldn’t help with c that much

part A: ABD is similar to ACD

part B: with A being 90 degrees and it being split in 2 ABC and ACD are both 90 degrees leaving them to be congruent

part C: this is where i got stuck but i got 9 units which is trigonometry or something but i’ll give the info i have!

D is 90 degrees so is angle A

ABD is 45 degrees

DB and angle A is 45 degrees

Step-by-step explanation:hope what i got helps

no this is a nonlinear negative

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
