The value of the expression in simplest form is: 55 8/17.
Hope this helps! :D

First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway thus

solve for "x"
The value of the sine, cosine and tangent of the figure will be found as follows:
a] Sine
sin x=(opposite)/(hypotenuse)
opposite=7
hypotenuse=25
thus:
sin x= 7/25
b] Cosine
cos x=adjacent/hypotensue
adjacent=24
hypotenuse=25
cos x=24/25
Tangent
Tan x=opposite/adajcent
opposite=7
adjacent=24
thus
tan x=7/24

Answer:
CD = 4
Step-by-step explanation:
GH bisects CF <u><em>means</em></u> CF = 2 CD
CF = 2 CD
⇔ 2y - 2 = 2×(3y - 11)
⇔ 2y - 2 = 6y - 22
⇔ 22 - 2 = 6y - 2y
⇔ 20 = 4y
⇔ y = 5
<u>Calculating CD ,For y = 5</u> :
CD = 3y - 11
= 3(5) - 11
= 15 - 11
= 4
