Question

11. If the three angles of a triangle are x+ 10 , x +20 , x+30 respectively , find them also express what type of triangle it is?

Answer 1

Answer:

X+10+X+20+X+30=180

X=40

Step-by-step explanation:

ACUTE ANGLE TRIANGLE

Answer 2

Answer:

1st angle= x+10

2nd angle=x+20

3rd angle=x+30

x+10+x+20+x+30=180 (angle sum property)

3x+60=180

3x=180-60=120

x=120/3 = 40 degree

therefore,

1st angle=40+10=50 degree

2nd angle= 40+20= 60 degree

3rd angle= 40+30= 70 degree

Step-by-step explanation:

it is a scalene triangle

hope it helps!!!
