Answer:
B
Step-by-step explanation:
Given
x² + 3x + 2 = 0
To factor the quadratic
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are 2 and 1, since
2 × 1 = 2 and 2 + 1 = 3, thus
(x + 2)(x + 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1
2020 + <em>N</em> ≡ 0 (mod 11)
<em>N</em> ≡ -2020 (mod 11)
Notice that 2020 = 183 • 11 + 7, so
<em>N</em> ≡ -(183 • 11 + 7) (mod 11)
<em>N</em> ≡ -7 (mod 11)
<em>N</em> ≡ 4 (mod 11)
It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
