Answer:
25 degrees
Step-by-step explanation:
Haha, awesome! Just did a problem like this!
All angles add up to 180, so set it up like this:
2x + 1 + 5x + 5 + 90 = 18
Combine like terms.
7x + 96 = 180
7x = 84
x = 12
Plug x back into 2x + 1
2(12) + 1
24 + 1
= 25 degrees
While we're at it...
5(12) + 5
60 + 5
= 65 degrees (for the other angle)
25 + 65 + 90 = 180
Math checks out & we're good to go!
Hope this helped. :) <3
Answer:
30/54
Step-by-step explanation:
1st make and equation so 5/9=x/54
now cross-multiply.
5/9=x/54
(5)*(54)=x*(9)
270=9x
you can flip the equation.
9x=270 (next divide both sides by 9)
x=30
so 30/54=5/9
hope this helps :)
