Answer:the population of brook trout
Step-by-step explanation:
∠A, ∠B, ∠C - interior angles of a triangle.
∠A 1 , ∠B 1 , ∠C 1 - exterior angles of a triangle.
∠A + ∠B + ∠C = 180°
∠A + ∠A 1 = 180°
Therefore: ∠A 1 = ∠B + ∠C ( two remote interior angles )
Answer:
An exterior angle of a triangle is equal to the sum of the two remote interior angles.
Answer:
<em>C. 1/60</em>
Step-by-step explanation:
Probability of 3 on a cube: 1 / 6
Probability of 9 from cards 1-10: 1/10
1/6 x 1/10 = 1/60
Answer:
120°
Step-by-step explanation:
Take half of the coeff. of x (which is 6), and then square the result: 3^2 = 9.
Then <span>x^2-6x + 9 - 9, and
x^2 - 6x + 9 is a perfect square trinomial.
