Vtriangle d e f is shown. angle e f d is a right angle. the length of e f is 24 and the length of d f is 7.
which trigonometric ratios are correct for triangle def? select three options.
sin(d) = startfraction 24 over 25 endfraction
cos(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 24 over 7 endfraction
sin(e) = startfraction 7 over 25 endfraction
tan(d) = startfraction 7 over 24 endfraction

$20.01

step-by-step explanation:

the sale price is (1.00 - 0.77)($87), or 0.23($87), or $20.01.

the answer is:

mean: 6

mad: 2.14

-1   1/6.   you dont subtract the denominators

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
