Find sin D sin E cos D and cos E

Andrew [12]

9514 1404 393

Answer:

sin(D) = cos(E) = (√3)/2

cos(D) = sin(E) = 1/2

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationships between trig functions and right triangle sides.

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

For this diagram, this means ...

sin(D) = cos(E) = (13√3)/26 = (√3)/2

cos(D) = sin(E) = 13/26 = 1/2

Anita and Joelle bowled together and their combined total score for one game was 425 points. Anita’s score was 40 less than twic

wariber [46]

Call Anita's score $"y"$ and Joelle's score $"x"$ .

1) "<span>their combined total score for one game was 425 points"
</span>Therefore $x+y=425$

2)"Anita’s score was 40 less than twice Joelle’s."
Therefore $y=2x-40$

Substitute:
$x+2x-40=425$

Solve:
$3x=465$
$x=155$

Backsubstitute:
$y=2x-40$
$y=2(155)-40$
$y=270$
