Well if the alloy makes the 1000 grams, but you are dealing with copper that isn't even 100% copper, than you either need 55% more copper, which isn't given, which means you really need 550 grams of alloy copper.
We have to use pythagorean theorem. The equation is

so we plug in the numbers (hypothenuse is always C in the equation)

now we solve:

a=6 Square Root
x=6 Answer
IF IT EQUALS 0
1. find two number that multiplied to 48 and adds to 14, which are 6 and 8.
2. substitute the new numbers in with x to get x^2 + 6x + 8x + 48.
3. factor out the x and the 8 to get x(x+6)+8(x+6).
4. x = -6, x = -8
IF IT DOES NOT EQUAL 0
then (x+6)*(x+8) is your answer.
Answer:
x=40°
Step-by-step explanation:
(x-5)+(x+15)=90°
2x+10=90
2x=80
x=40°
