In ΔXYZ, x = 27 cm, y = 79 cm and ∠Z=142°. Find the length of z, to the nearest centimeter.
Annette [7]

The value of side z will be equal to 99.32 cm.

<h3>What is trigonometry?</h3>

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle are termed trigonometry.

Given that:-

In ΔXYZ, x = 27 cm, y = 79 cm and ∠Z=142°

So by applying the formula given below:-

z²   =   x²  +  y²  -  2xyCos(142)

z²   =   79²  +   27²   -  2 ( 79 x 27  x  Cos142  )

z    =    99.32  cm

Hence the value of side z will be equal to 99.32 cm.

PLEASE HELP......<br> brainliest....URGENT
evablogger [386]

Answer:

see below

Step-by-step explanation:

1)  see attached image

2) <u> bearings from A to B</u>

Note: bearing is always clockwise from A and from North.

(i)

bearing 180° + 67°

247° from N

(ii)

bearing 148 + 180

328° from N

(iii)

bearing 180 - 21

159° from N

(iv)

39° from N 

(v)

bearing 90 - 40

50° from N

3) <u>back bearing from each diagram on no. 2</u>

<u />

Note: subtract 200 if bearing is more than 180

         add 180 if the bearing is less than 180

(i) 247 - 200 = 47°

(ii) 328 - 200 = 128°

(iii) 159 + 180 = 339°

(iv) 39 + 180 = 219°

(v) 50 + 180 = 230°

Number of distinct fruits purcahed = 6

Number of ounces of each fruit = 5 1/3

The total ounces of fruits purchased :

(Number of distinct fruits purchased * Number of ounces of each fruit)

6 * 5 1/3 = 6 * 16/3

6 * 16/3 = (16 * 6) / 3 = 96 /3 = 32 ounces of fruits.
