Given:

In the given triangle the measure of two angles are 102 degree and 28 degrees and the sides of the triangle are a, 27 cm, c.

To find:

The value of a.

Solution:

Let the given triangle be ABC, such that,

m\angle B=28^\circ

m\angle C=102^\circ

b=27\ cm

Using angle sum property of triangles, we get

m\angle A+m\angle B+m\angle C=180^\circ

m\angle A+28^\circ+102^\circ=180^\circ

m\angle A=180^\circ-28^\circ-102^\circ

m\angle A=50^\circ

According to the Law of Sines:

\dfrac{\sin A}{a}=\dfrac{\sin B}{b}

\dfrac{\sin 50^\circ }{a}=\dfrac{\sin 28^\circ }{27}

\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a

\dfrac{27\times \sin 50^\circ }{\sin 28^\circ}=a

a\approx 44.06

Therefore, the value of a is about 44.06 cm.

When Θ = 5 pi over 6, what are the reference angle and the sign values for sine, cosine, and tangent?
nikklg [1K]
Ф =5π/6
The reference angle is the smallest angle that the terminal side of the angle makes with the x-axis.

Given that here π/2 < Ф < π, the angle is in the second quadrant.

In the second quadrant the signs are:

sine positive
cosine negative
tangent negative.

Furthermore, the reference angle is π - Ф = π - 5π/6 = π/6.

Then,

sin Ф = sin π/6 = 1/2
cos Ф = - cos π/6 = -√(3) / 2
tan Ф = - tan π/6 = -√(3) /3
