In ΔUVW, w = 9 cm, v = 2.2 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.
Alja [10]

Complete Question

In ΔUVW, w = 9 cm, v = 22 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.

Answer:

16.5°

Step-by-step explanation:

In ΔUVW, w = 9 cm, v = 22 cm and ∠V=136°. Find all possible values of ∠W, to the nearest 10th of a degree.

We solve using Sine rule formula

a/sin A = b/sin B

We are solving for angle W

∠V=136°

Hence:

22 /sin 136 = 9 /sin W

Cross Multiply

22 × sin W = sin 136 × 9

sin W = sin 136 × 9/22

W = arc sin [sin 136 × 9/2.2]

W = 16.50975°

W = 16.5°

What system of equations is shown on the graph below?
erma4kov [3.2K]

Answer:

The equation of the line passing through the points (-2,0) and (0,-4)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}

\frac{y - 0}{x  - ( -  2)}  =  \frac{ - 4 - 0}{0 - ( - 2)}  =  \frac{ - 4}{2}  =  - 2

y =  - 2(x + 2) \\ y =  - 2x - 4

2x + y =  - 4

The equation of the line passing through the points (0,-2) and (4,0)

\frac{y - y1}{x - x1}  =  \frac{y2 - y1}{x2 - x1}  \:

\frac{y - ( - 2)}{x - 0}  =  \frac{0 - ( - 2)}{4 - 0}

\frac{y + 2}{x}  =  \frac{1}{2}

x - 2y = 4

Option B

x minus 2 y = 4 and 2 x + y = negative 4
