Question

The
measures of angles of a triangle are xº, (x-
10). (x-50)​

Answer 1

Answer:

x+x-10+x-50=180(angle sum property of triangle)

3x=180-60

3x =120

X=120/3

X =40

Step-by-step explanation:

All the angles are in degree=40,30,90

Answer 2

To Find:-

• The measure of angles of a triangle

Given:-

• The angles of a triangle are:-
• x° , ( x - 10 )° and ( x - 50 )°

Solution:-

According the question,

We know that the measure of a triangle is 180°

So,

⟹ x + x - 10 + x - 50 = 180

⟹ 3x = 180 + 50 + 10

⟹ 3x = 240

⟹ x = 240/3

⟹ x = 80

• The value of angles are:-

➡ 1st angle

⟹ x = 80°

➡ 2nd angle

⟹ ( x - 10 )

⟹ ( 80 - 10 )

⟹ 70°

➡ 3rd angle

⟹ ( x - 50 )

⟹ ( 80 - 50 )

⟹ 30°

Now, Verification

⟹ 80° + 70° + 30° = 180°

⟹ 150° + 30° = 180°

⟹ 180° = 180°

L.H.S = R.H.S

Hence, Proved.
