100 POINTS AND BRAINLIEST!! PRE CALC Given the sign x = 3/5, sin y = 7/25, and x and y are both acute angles, the value of tan (x - y) is

a. 39/32
b. 44/117
c. 44/7
d. 4/3

Please explain your answer :)

b

Step-by-step explanation:

sin x = =

This is a 3- 4- 5 right triangle

with adjacent side = 4 , then

cos x = = , thus

tan x = = = × =

---------------------------------------------------

sin y =

This is a 7- 24- 25 right triangle

with adjacent side = 24 , then

cos y = = , thus

tan y = = = × =

----------------------------------------------------

tan(x - y) =

             =

             =

             =

             = ×

             = ×

             = → b

yes yes yes yes yes yes yes yes yes

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
