Answer:
90 degrees
Step-by-step explanation:
the answer is 90 degrees because when the triangle is a right triangle, the two smaller angles equal 90 degrees.
4x^2 + 5xy - y^2 = 6
Implicitly differentiating both sides,
4(2x) + 5(x y' + y) - 2yy' = 0
where y' = dy/dx
8x + 5xy' +5y -2yy' = 0
combining y' terms
y' (5x-2y) +8x +5y = 0
y'(5x-2y) = -(8x+5y)
dy/dx = -(8x+5y)/(5x-2y)
or
dy/dx = (8x+5y)/(2y-5x)
Answer:
a = 15, b = 7, c = 5, d = 10, e = 12
Step-by-step explanation:
You only need to find d.
22+d=32, d=10
Only one choice has d=10
Don't waste time checking the others.
