A central angle of a circle measures 42 degrees. What else can be shown to measure 42 degrees?
Slav-nsk [51]

Answer:

Vertically opposite angles

Step-by-step explanation:

Given

\theta = 42^\circ

Required

What else can measure \theta = 42^\circ

The question has missing options. So, I will give a general explanation.

Using the attached image as a point of reference.

Given that:

\theta = 42^\circ

The value of b is calculated as:

b = \theta

Because b and \theta are vertically opposite angles

<em>This gives:</em>

<em></em>b = 42^\circ<em></em>

<em></em>

<em>So, one possible answer to the question is a vertically opposite angle</em>

Classify the triangle with the given side lengths as acute, right, obtuse, or not a triangle:
slavikrds [6]

Answer:

It is not a right triangles because 15^2 + 13^2 is NOT EQUAL to 19^2

let x, y, and z be the angles inside the triangle.

Law of cosines says:

19^2 = 13^2 + 15^2 - 2(13)(15)cos x

361 = 169 + 225 - 390 cos x

-33 = -390 cos x

-33/-390 = cos x

11/130 = cos x

x = inverse cosine (11/130)

= 85.14609471338569.....

Per law of sines:

sin x/19 = sin y / 13

(13/19)sinx = sin y

inverse_sine ( (13/19) sin x) = y

y = 42.9810733896016548....

Per law of sines

sin x/19 = sin z / 15

z = inverse_sine( (15/19) sin x)

= 51.8728352950227805....

So it is an acute triangle and yes, these angles add up to 180

The tour costs £359 per person. You have to pay a deposit of £78 in advance. How much more do you need to pay
dimaraw [331]
The cost of the tour= £359.

The deposit is just an initial pay, which is a part payment of the total cost

If you pay a deposit of £78 out of £359, Then you need to subtract £78 from £359 to obtain,

359-78=281 pounds.

Therefore you need to pay £281 more.
