Triangle X Y Z is shown. Angle X Y Z is 75 degrees and angle Y Z X is 50 degrees. The length of X Y is 2 and the length of Y Z i

zalisa [80]

The third angle of the triangle will be 60°. The nearest value of x is 2.1 units. Then the correct option is B.

<h3>What is the law of sines?</h3>

For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,

we have, by law of sines,

$\rm \dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}$

Triangle XYZ is shown.

Angle XYZ is 75 degrees and angle YZX is 50 degrees.

The length of XY is 2 and the length of YZ is x.

Then the third angle of the triangle will be

⇒ 180° - 50° - 70°

⇒60°

Then we have

x / sin 60° = 2 / sin 50°

x = 2.26

Then the nearest value of x is 2.1 units.

Then the correct option is B.

When Jerrie bought her Honda, the odometer

Deffense [45]

Answer:

1,243 miles

Step-by-step explanation:

The original value is: 18,146 miles

The new values is: 33,062 miles

The increase is hence: <em>The original value subtracted from the new value</em>

33062 - 18146 = 14916

The increase is 14,916 miles which has been gained over 12 months

The average miles per month can be gotten by dividing the increase by 12

14916 ÷ 12 = 1243

∴ On average, Jerrie has driven 1,243 miles per month

The internal dimension of a lidless wooden box is 48cm × 38cm × 32cm. If the thickness of the tank is 1 cm, find the volume of t

Stells [14]

Step-by-step explanation:

this is confusing.

first the description says "the internal dimensions".

and then it tells us the thickness of the tank walls (1cm).

so, I am not sure what the given numbers describe.

in any case, the volume is length × width × height.

so, either

48×38×32

46×36×31 (as for length and width we need to consider 2 walls, one on each end, for the height only one wall, as the tank is open and lidless.

whatever you choose, make sure to mark the result as cm³.
