Given ABC, what is the measure of A ?

m A = __________ degrees

Answer 1

`▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪`

we know that, sum of all interior angles of a triangle is 180°

so,

• 
  `3x + 1 + 2x - 15 + x + 14 = 180`

• 
  `6x = 180`

• 
  `x = (180)/(6)`

• 
  `x = 30 \degree`

Let's find Angle A :

• 
  `x + 14`

• 
  `30 + 14`

• 
  `44 \degree`

hope it helps....

Answer 2

<A = 44

Explanation:

The sum of the angles of a triangle is 180

3x+1 + 2x-15 + x+14 = 180

Combine like terms

6x =180

Divide by 6

6x/6 = 180/6

x =30

Angle A = x+14 = 30+14 = 44
