If we let m₁, m₂, and m₃ be the measures of the angles of the triangle, the equation that would relate them to each other is,
     m₁ + m₂ + m₃ = 180
Given the measures of the first two angles, the measure of the third angle is calculated through the equation,
    m₃ = 180 - (m₁ + m₂)
Substituting the known expressions,
    m₃ = 180 - (-3x⁵ + 2x²)
Simplifying,
<em>    m₃ = 180 + 3x⁵ - 2x²</em>

Answer:
R = (- 3.5, - 7 )
Step-by-step explanation:
Using the Section formula
 =
 =  =
 =  =
 =  = - 3.5
 = - 3.5
 =
 =  =
 =  =
 =  = - 7
 = - 7
Thus coordinates of R = (- 3.5, - 7 )
