Answer:
the answer is x = 7
Step-by-step explanation:
1) replace the x with 7
2) 7 + 16 = 23
3) 4(7) = 28
4) 28 - 5 = 23
they're both equal as perpendicular angles should be!
5x-y=3
Not sure if it’s correct
20% is .20/ 20/50 is 40% or .4 or 4/10/ 9% is .09 or 9/100 / 9/10 is 90% or .9/ 66% is .66 or 33/50 or 66/100/ 6/10 is 60% or 60/100 or .6/ 2% is .02 or 1/50 or 2/100. I didn't exactly understand the question, but I hope this answers your question.
x=angle CDB (vertical angles)
=angle ABE (corresponding angles, AB parallel to CD)
=132-90 (exterior angle 132=sum of angles ABE and AEB)
=42 degrees
Answer:
sin(x) = 
x = 16.26°
Step-by-step explanation:
First use Pythagorean theorem to find the length of the hypotenuse. Use 
. Since we know a and b we can plug in to find c. When we plug in we get: 
. When we solve this out we get 25 = c.
Now that we know the value of c, we also know sin(x) = 
. Using this we see that sin(x) = .
To get the exact degree value of x, take the inverse sin of :
which gives us 16.26020° rounded to 16.26°
