Question

the measure of the angles of a triangle are (5x + 10) degree. (3x + 15) degree and (x + 20) degree respectively. what type of triangle is it ? ​

Answer 1

Answer:

(5x+10)+(3x+15)+(x+20)=180( angle sum property of triangle)

9x+45=180°

9x=180-45=135

x=135/9

x=15°

1st angle= (5(15)+10)= 75+10=85°

2nd angle= (3(15)+15)=45+15=60

3rd angle = 15+20=35°

Since all angles are less than 90° it is an acute angles triangle
