Answer:

40°

Step-by-step explanation:

Measure of Nonagon (9-sided polygon) = 1260°

Each angle measure = 1260 ÷ 9 = 140°

The value of x (the outside angle) = 180° - 140° = 40°

German County is planning to expand its train service. In studying the current service, the county planner looked at which train

mash [69]

Answer:

a. Blue and orange train lines

b. 2

c. Cadiz York

Step-by-step explanation:

Given: Venn diagram

To find:

a. train lines that have a stop at Jena

b. Number of stations along both the Purple Line and the Blue Line

c. stations that are along all three lines

Solution:

A Venn diagram is a pictorial representation of mathematical sets such that as circles are drawn within a rectangle which represents an universal set.

a. Blue and orange train lines have a stop at Jena.

b. Volos Bern and Cadiz York lie in the intersecting part of blue line stations and purple line stations.

So,

Number of stations along both the Purple Line and the Blue Line = 2

c. Cadiz York lie in the intersecting part of blue line stations, purple line stations and orange line stations.

So, Cadiz York lie along all three lines

How many triangles does a=6 b=10 A=33° create?

GaryK [48]

Answer:

2 triangles are possible.

Step-by-step explanation:

Given

a=6

b=10

$\angle$ A=33°

To find:

Number of triangles possible ?

Solution:

First of all, let us use the <em>sine rule</em>:

As per Sine Rule:

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

And let us find the angle B.

$\dfrac{6}{sin33}=\dfrac{10}{sinB}\\sinB = \dfrac{10}{6}\times sin33\\B =sin^{-1}(1.67 \times 0.545)\\B =sin^{-1}(0.9095) =65.44^\circ$

This value is in the 1st quadrant i.e. acute angle.

One more value for B is possible in the 2nd quadrant i.e. obtuse angle which is: 180 - 65.44 = $114.56^\circ$

For the value of $\angle B = 65.44^\circ$ , let us find $\angle C$ :

$\angle A+\angle B+\angle C = 180^\circ\\\Rightarrow 33+65.44+\angle C = 180\\\Rightarrow \angle C = 180-98.44 = 81.56^\circ$

Let us find side c using sine rule again:

$\dfrac{6}{sin33}=\dfrac{c}{sin81.56^\circ}\\\Rightarrow c = 11.02 \times sin81.56^\circ = 10.89$

So, one possible triangle is:

a = 6, b = 10, c = 10.89

$\angle$ A=33°, $\angle$ A=65.44°, $\angle$ C=81.56°

For the value of $\angle B =$ $114.56^\circ$ , let us find $\angle C$ :

$\angle A+\angle B+\angle C = 180^\circ\\\Rightarrow 33+114.56+\angle C = 180\\\Rightarrow \angle C = 180-147.56 = 32.44^\circ$

Let us find side c using sine rule again:

$\dfrac{6}{sin33}=\dfrac{c}{sin32.44^\circ}\\\Rightarrow c = 11.02 \times sin32.44^\circ = 5.91$

So, second possible triangle is:

a = 6, b = 10, c = 5.91

$\angle$ A=33°, $\angle$ A=114.56°, $\angle$ C=32.44°

So, answer is : 2 triangles are possible.
