first you have to find the triangle, then you can move to the actual question.

x+30+80 = 180

x+110 = 180

x+110 - 110 = 180-110

x =70

now you can go to the actual question.

y + 70 = 180

y+70- 70 = 180-70

y = 110

there is your answer. hope this is helpful

What is the length of CD ? In this diagram ABC EDC ?<br> Please help !!!!
n200080 [17]
Answer:
CD = x = 4 units

Explanation:
We are given that the two triangles are similar. This means that we can set the similarity proportionality as follows:
\frac{BC}{CD} =  \frac{CA}{CE} =  \frac{AB}{ED}

W e have:
BC = 20 - x
AC = 20
CD = x
CE = 5

Substitute in the above proportionality and solve for x as follows:
\frac{20-x}{x} =  \frac{20}{5} = 4

4x = 20 - x
5x = 20
x = 4

Based on he above:
CD = 4 units
BC = 20 - x = 20 - 4 = 16 units

Hope this helps :)

Which expression is equivalent to -9x^-1y^-1 / -15x^5 y^-3 Assume x = 0 y = 0
jenyasd209 [6]
For this case we have the following expression:
   -9x ^ -1y ^ -1 / -15x ^ 5 y ^ -3
 For power properties we have:
   -9x ^ (- 1-5) y ^ (- 1 - (- 3)) / - 15
 Rewriting we have:
   9x ^ (- 6) y ^ (- 1 + 3) / 15
   3x ^ (- 6) y ^ (2) / 5
   3y ^ 2 / 5x ^ 6
 Answer:
 
  3y ^ 2 / 5x ^ 6Note: answer is not between the options. Rewrite the expression again, or the options.

What is 7.5% written as a fraction in simplest form
weqwewe [10]
3\4 ! you simply convert 7.5% into a fraction. (move the decimal point to the right two times. This should give you 75. Remember to put 75 over 100.
EX: 75/100
Next you must find the greatest common fact of both numbers. In this case the number is 25.
25 goes into 75 3 times. So that is your numerator or the number on top.
25 goes into 100 4 times. This will be your denominator or the number on the bottom.
Your answer should be 3/4! Make sure to show your work! good luck!
