Math Problem Statement

How do you solve for x on this triangle

Solution

To solve for the length of side xx in this triangle, we can use the Law of Sines, which states:

asinA=bsinB=csinC\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}

where a,b,ca, b, c are the sides opposite the angles A,B,CA, B, C respectively.

The angles given are:

  • A=32A = 32^\circ (opposite to side xx)
  • B=48B = 48^\circ (opposite to side 66)
  • C=1803248=100C = 180^\circ - 32^\circ - 48^\circ = 100^\circ (third angle of the triangle)

Using the Law of Sines:

xsin(32)=6sin(48)\frac{x}{\sin(32^\circ)} = \frac{6}{\sin(48^\circ)}

Now, let's solve for xx:

x=6sin(32)sin(48)x = \frac{6 \cdot \sin(32^\circ)}{\sin(48^\circ)}

Let's calculate the value of xx.The length of side xx is approximately 4.284.28 units.
