My recommendation would be to factor..
x² + 4x + 3 = 0 factor the left side into two binomials
(x + 3)(x + 1) = 0 set each of these binomials equal to zero and solve
x + 3 = 0 Implies x = -3
x + 1 = 0 implies x = -1
Answer:
0.7246 radians
Step-by-step explanation:
According to the Question,
Given that, a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches
- The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:
d = √{ (12)² +(15)² } = √(144+225) = √369inches
- The tangent of the angle is the ratio of the height of the box to this length
Tan∅ = 17/√369
Taking the
, we have
∅ =
(17/√369) ≈ 0.7246 radians

<h3>Yes the triangles are congruent by ASA axiom or congruency .</h3>
Because one side of triangle is equal and two angles are equal . So option 1 is your answer .
