Step-by-step explanation:

$\frac{x - 9}{15} = \frac{2x - 9}{10} \\$

$\frac{x - 9}{3} = \frac{2x - 9}{2} \\$

$2( x - 9) = 3(2x - 9) \\$

$2x - 18 = 6x - 27$

$27 - 18 = 6x - 2x$

$9 = 4x$

$x = \frac{9}{4} \\$

Two sides and an angle (SSA) of a triangle are given. Determine if the given measurements produce one triangle, two triangles, o

Mariana [72]

Answer:

1. c = 28.1, A = 19°, C = 144°

2. c = 2.0, A = 161°, C = 2°

Step-by-step explanation:

In general, if the given angle is not opposite the longest side, there will be two solutions. That is the case here.

Angle A can be found from the law of sines. It will be ...

A = arcsin(a/b·sin(b)) = arcsin(15.73/13.8·sin(17°)) ≈ arcsin(0.333261) ≈ 19.46°

or the supplement of that, 160.54°.

Angle C will be the angle required to make the sum of angles be 180°, either 143.53° or 2.47°.

Side c will be ...

c = b·sin(C)/sin(B) ≈ 47.2002×sin(C)

either 28.053 or 2.032.

There are two possible triangles:

(A, C, c) = (19°, 144°, 28.1) or (161°, 2°, 2.0)

slega [8]

Answer:

475

Step-by-step explanation:

To find the cost of the bench, subtract 99 from 1049, then divide by 2. Add 99 to the answer(475) to get the cost of the garden table(574).
