Answer:

  x = 4

  y = 2

Step-by-step explanation:

The triangles being similar means the side ratios are the same.

  AB/FD = BC/DE   and   AB/FD = CA/EF

  12/3 = (3x+8)/5   and   12/3 = 28/(y+5)

Multiplying by 5, the first equation becomes ...

  20 = 3x +8

  12 = 3x . . . . . . subtract 8

  4 = x . . . . . . . . divide by 3

__

Multiplying by (y+5)/4, the second equation becomes ...

  y +5 = 28/4

  y = 2 . . . . . . . . subtract 5

What is the measure of angle A?
antoniya [11.8K]

Answer:

A = 19.47

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hypotenuse

sin A = 2/6

Take the inverse sin of each side

sin ^-1 ( sin A) = sin ^-1 (2/6)

A =19.47122063

To the nearest hundredth

A = 19.47

Anuta_ua [19.1K]

I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.
