Isolate x. First, add 2/5 to both sides
x - 2/5 (+2/5) = 1/3 (+2/5)
x = 1/3 + 2/5
to simplify, find common denominators (15 in this case). Multiply the same number to both the denominator and numerator
(1/3)(5/5) = 5/15
(2/5)(3/3) = 6/15
x = 5/15 + 6/15
Simplify
x = 11/15
11/15 is your answer for x
hope this helps
8 * 3/4 = 24/4
24/4 = 6
The answer is 6.
Hope this helped☺☺
10^2 + 5^2 = Diagonal length. so, 100 + 25 = 125 diagonal length
So if you find the length of 2 of the sides then you find the length of the other two, so now you have all the side lengths. You add all the lengths up and then you have your perimeter.
Answer:
Let the angle be "x".
Its supplement is "8x".
-------------
Step-by-step explanation:
x + 8x = 180
9x = 180
x = 20 degrees
8x = 8*20 = 160 degrees
