7 0

Answer:

3, 5, 8, 13

Step-by-step explanation:

aₙ = aₙ₋₁ + aₙ₋₂

a₃ = a₂ + a₁ = 2 + 1 = 3

a₄ = a₃ + a₂ = 3 + 2 = 5

a₅ = a₄ + a₃ = 5 + 3 = 8

a₆ = a₅ + a₄ = 8 + 5 = 13

Is -0.44 bigger then 4.35
TEA [102]

Answer: No.

Step-by-step explanation:

1. It is negative. -0.44. Any negative number compared to a positive number when you compare which is the larger number, the positive number will always be greater.

2. The 4 in the number 4.35 is a whole number. However, the whole number in -0.44 is, well zero. Just by looking at that, you can tell that 4.35 is the larger number.

Hope that helps :))

Answer:

∠A = 70°, ∠B = 50°, and ∠C = 60°.

Step-by-step explanation:

In a triangle ΔABC, ∠A + ∠B + ∠C = 180° ......... (1), we know from the property of triangle.

Now, the sum of ∠C and the exterior angle adjacent to ∠C is 180°.

If the exterior angle adjacent to ∠C is 120°, then ∠C = 180° - 120° = 60°.

Now, from equation (1), ∠A + ∠B = 180° - ∠C = 180° - 60° = 120° ......... (2)

Now, given that ∠A = 2x and ∠B = x + 15.

Hence, from equation (2), we have, 2x + x + 15 = 120

⇒ 3x = 105

⇒ x = 35.

Therefore, ∠A = 2x = 2 × 35 = 70°

∠B = x + 15 = 35 + 15 = 50°

and ∠C = 60° (Answer)
