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
250cm^2 is the answer... I think...
Answer: 2:3 and 12:18
Step-by-step explanation: Find the multiples of 6 and 9
We want 4/5 of a number to be 144. This means that

Multiplying both sides by 5/4, we have
