Kelsey has already spent 42 minutes on the phone, and she expects to spend 2 more minutes
grandymaker [24]

Answer:

11 calls

Step-by-step explanation:

She has already spent 42 min. Also she wants to talk for 2 min per call. We can change calls on x. So, only 2x min for her calls left.

42 + 2x = 64

2x = 64 - 42

2x= 22

x=11

What is the answer to this question?

Angle A of triangle ABC will be ...
  ∠A = θ₂ -θ₃ = 77° -26° = 51°
Angle B of triangle ABC will be ...
  ∠B = 180° -θ₂ -θ₁ = 180° -77° -44° = 59°
Then angle C will be ...
  ∠C = 180° -∠A -∠B = 180° -51° -59° = 70°

By the Law of Sines,
  a/sin(∠A) = c/sin(∠C)
  a = c×sin(∠A)/sin(∠C)
  a = (57 yd)×sin(51°)/sin(70°) ≈ 47.14 yd

The distance from B to C is 47.14 yd.
