Hope this helps if need more pls text✌
'Complement' = difference between an angle an 90 degrees.
'Supplement' = difference between an angle and 180 degrees.
Complement of A = 90 - A
Supplement of A = 180 - A
The problem says that the complement is 1/6 of the supplement, right ?
So <u> 90 - A = (1/6) x (180 - A)</u>
Multiply each side of this equation by 6 :
540 - 6 A = 180 - A
Subtract 180 from each side:
360 - 6 A = - A
Add 6A to each side :
360 = 5 A
Divide each side by 5 :
<u>A = 72°</u>
Answer:
-4 and 5
Step-by-step explanation:
4*5 = x(x-1) ; cross multiply
20 = x²-x ; distribute multiplication over subtraction
x²-x-20 =0; subtract 20 from both sides
(x+4) (x-5) = 0; factor
x+4 =0 gives x = -4
x-5 =0 gives x = 5
