Which equation can be used to solve for b?

Mathematics
1 answer:
Tanya [424]3 years ago
8 0

Answer:

The first one

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan30° = \frac{opposite}{adjacent} = \frac{AC}{BC} = \frac{b}{8}

Multiply both sides by 8

8 × tan30° = b, that is

b = 8tan30°

In AABC, MZA = 16°, mZB = 49°, and<br> a = 4. Find c to the nearest tenth.
zhannawk [14.2K]

Answer:

  (c)  13.2

Step-by-step explanation:

The sum of angles in a triangle is 180°, so angle C is ...

  C = 180° -A -B

  C = 180° -16° -49° = 115°

The measure of side c can be found from the Law of Sines:

  c/sin(C) = a/sin(A)

  c = a·sin(C)/sin(A) = 4·sin(115°)/sin(16°)

  c ≈ 13.2
