The angle is 35 degrees
(180 - x) = 2(90 - x) + 35
180 - x = 180 - 2x + 35
180 - x = 215 - 2x
180 + x = 215
x = 35
Check:
180 - 35 = 145 supplement
90 - 35 = 55 complement
55*2 = 110 twice the complement
110 + 35 = 145 :)
Answer:
Step-by-step explanation:
For an expression to be a difference of squares, it must be a difference of two terms, each of which is a square. A term is a square if its coefficient is a square and if its degree is even.
The third expression is a sum, not a difference; the fourth expression has a term that is not a square (40). Neither of those is a difference of squares.
12. You divide 30 by 5 to get 4. Then multiply 4 by 3 to get 12. You need 12 oz of red. Hope this helps!
