Answer:

10. Not enough information

11. B ≈ 12.0°

12. A ≈ 34.1°

Step-by-step explanation:

10. Not enough information

11.

We need to use the Law of Sines, which states that for a triangle with lengths a, b, and c and angles A, B, and C:

$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Here, we can say that AB = c = 38, C = 128, and AC = b = 10. Plug these in to find B:

$\frac{b}{sinB} =\frac{c}{sinC}$

$\frac{10}{sinB} =\frac{38}{sin128}$

Solve for B:

B ≈ 12.0°

12.

Use the Law of Sines as above.

$\frac{a}{sinA} =\frac{b}{sinB}$

$\frac{23}{sinA} =\frac{28}{sin(43)}$

Solve for A:

A ≈ 34.1°

Find the point on the terminal side of θ = -3<img src="https://tex.z-dn.net/?f=%20%5Cpi%20" id="TexFormula1" title=" \pi " alt="

viktelen [127]

This is in the third quadrant where the tangent of the angle is positive

tan pi/4 = 1 = y/-1 so y = -1

The required point is (-1,-1)
