The measures of the angles

Expert Solution & Answer
Check Mark

Answer to Problem 20CR

The measures of the angles are 39.5∘,48.5∘, and 92∘

Explanation of Solution

Given information:

The angle measures of a triangle are (x−9)∘,x∘ and (2x−5)∘

Concept used:

The sum of the angle measures is 180

Rules of Addition/ Subtraction:

  • Two numbers with similar sign always get added and the resulting number will carry the similar sign.
  • Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.

Calculation:

In order to find the measure of the angle as shown below

  The sum of the angle measures =180∘180=(x−9)+x+(2x−5)180=x−9+x+2x−5180=2x+2x−9−5180=4x−14180+14=4x−14+14194=4x1944=4x448.5∘=x⇒x=48.5∘

The angle of measures are:

  (x−9)∘,x∘ and (2x−5)∘x∘=48.5∘(x−9)∘=(48.5−9)=39.5∘(2x−5)∘=(2×48.5−5)∘=(97−5)∘=92∘

Thus, the measures of the angles are 39.5∘,48.5∘, and 92∘
