In XYZ, X = 8.3 meters, y = 9 meters, and z = 15 meters. Find the remaining measurements of the triangle, and round your answers to the nearest tenth.

X = 56.9°, Y = 66.6°, Z = 56.5°

X = 28.6°, Y = 31.2°, Z= 120.2

X = 56.9°, Y = 66.6°, Z = 120.2°

X = 28.6°, Y = 31.2°, Z = 56.5°

The correct option is Second one X = 28.6°, Y = 31.2°, Z= 120.2

Therefore,

∠X = 28.6° , ∠Y = 31.2°, and ∠Z =120.2°

Step-by-step explanation:

Given:

In Δ XYZ such that Sides opposite to ∠X, ∠Y, and ∠Z are

x = 8.3 meters

y = 9 meters

z = 15 meters,

To Find:

∠X = ? , ∠Y = ?, and ∠Z = ?

Solution:

Cosine Rule In XYZ is given as

Substituting the given values in above formula we get

Similarly for Y

Similarly For Z

Therefore,

∠X = 28.6° , ∠Y = 31.2°, and ∠Z =120.2°

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
