Answer:

x = 82

Step-by-step explanation:

The bottom angle is the same as the angle next to x + 6

A straight angle is 180 degrees.

You add the given angles: (x + 6) + (x + 10) = 2x + 16

180 = 2x + 16

- 16 -16

164 = 2x

x = 82

nalin [4]

Answer:

a. 120 cables

Step-by-step explanation:

There are 4 boxes
Each box contains 30 cables
Total number of cables = 4*30 = 120

Purpose of the test = to confirm all cables are good

Population of interest in this case is all cables.

So the correct answer choice is

a. 120 cables

Find all the missing elements: B 14 15 70° A b с

photoshop1234 [79]

Answer:

$B=48.7\\$

$c=61.3$

$b=12$

Step-by-step explanation:

Using sines law for triangles,

$\frac{15}{sinA} =\frac{14}{sinc} =\frac{b}{sinB} \\\\A= 70$

⇒ $\frac{15}{sin70} =\frac{14}{sinC} =\frac{b}{sinB}$

⇒ $\frac{15}{0.9397} =\frac{14}{sinC}=\frac{b}{sinB}$

⇒ $15.9625=\frac{14}{sinC}$

⇒ $SinC=\frac{14}{15.9625}=0.8771$

⇒ $C=Sin^{-1}(0.8771)=61.29$

⇒ $C=61 ~ or ~ 61.30$

$\frac{b}{Sin B}=15.9625$

Now sum of angles a Δ is 180°

A+B+C=180°

$70+B+61=180$

$B=180-131=49~ or ~ 48.7$

$b=sin(48.70)(15.9625)=(0.7547)*(15.9625)= 12.0$
