Answer:
Step-by-step explanation:
adjacent=5 ,hypotenuse13 opposite=?
hypotenuse^2=opposite^2+adjacent^2
13^2=opposite^2+5^2
169-25=opposite^2
=opposite
12=opposite
SinA=opposite/hypotenuse
12/13
therefore sinA =`12/13
I need help using cosine and sine ratios to find the missing side lengths

Answer: x +
x = 2x - 25
Step-by-step explanation:
First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:
x +
x
Then it says the last part of the expression is "twenty five less than twice the number"
2x - 25
Then, equal the two parts of the equation to each other.
x +
x = 2x - 25
Hope this helps! :)
