Answer :

  • Angle A = 19.6°

Step-by-step explanation :

According to the question It is given that,

  • Angle A = x
  • Angle B = 5x
  • Angle C = 4x - 16

We will apply angle sum property in the question.

Angle sum property states that sum of all the angles of triangle is 180°


\: :\implies ∠A + ∠B + ∠ C = 180


\: :\implies x + 5x + 4x - 16 = 180


\: :\implies 10x - 16 = 180


\: :\implies 10x = 180 + 16


\: :\implies 10x = 196


\: :\implies x = 196/10


\: :\implies x = 19.6

Therefore, The Measure of Angle A is 19.6°

Answer:

x = 19.6

Explanation:

The sum of the angles of a triangle is 180.

<A + <B+ < C = 180

x + 5x + 4x - 16 = 180

Combine like terms.

10x-16=180

Add 16 to each side.

10x-16+16 = 180+16

10x = 196

Divide each side by 10.

10x/10 = 196/10

x = 19.6
