Answer:
x = 15
Step-by-step explanation:
I am going to use the "butterfly" method for proportions
(there is another type of butterfly method that is different, I am not sure if there is another name for this method, sorry!)
Multiply the:
- top left by the bottom right
-the top right by the bottom left
and then:
- set them equal to each other
So we will <u>multiply 7 by x and 21 by 5</u> (if this doesn't make sense tell me and I will explain it even more!)
7x = 21 * 5
7x = 105
(Divide both sides by 7) <em>x = 15</em>
Hope this helps, have a nice day! :D <3
What is the question exactly?
Answer: I believe the answer is 3.07 but I may be wrong so if you want you can wait for another answer :D
Step-by-step explanation:
All I saw there was area so just multiply 10.2 and 17 which is 173.4
Because it's a right angle, you can determine that Angle ABC and Angle CBD=90 degrees. Therefore:
(2x+1)+33=90
2x+1=57
2x=56
x=28
Due to one of the postulates, or whatever (haven't done geometry in 2 yrs, forgive me), angles GJH and FJI are equal to each other. Therefore:
5x+12=6x-10
-x=-22
x=22
