Step-by-step explanation:

so the angles of the triangles are A1+A2+A3=360

so (4x+7)+(11x-9)+32=360

combine like terms

15x+30=360

isolate the variable

15x=330

x=22

Answer: Question 28 answer is larynx

Question 29:The vocal cords are two bands of smooth muscle tissue found in the larynx. The vocal cords vibrate and air passes through the cords from the lungs to produce the sound of your voice.

Question 30:The vocal folds produce sound when they come together and then vibrate as air passes through them during exhalation of air from the lungs. This vibration produces the sound wave for your voice.

I just need a quick answer please help me?
Feliz [49]

Answer:

x = 2.

y =  6.

Step-by-step explanation:

Consider the triangle on the left.

Because there are 2 equal angles at the vertex on the bottom right:

3/9 = x/(8 - x)

1/3 = x / (8 - x)

3x = 8 - x

4x = 8

x = 2  (answer).

Similarly, for the second triangle:

3/y = 2/4

3/y = 1/2

y = 6

(answer).
