Question

three angles of a triangle are 3x, x+10 and 4x-30. Find the smallest angle of the triangle. please answer it fast.​

Answer 1

Answer:

we know the sum of the three angles of a triangle is 180°

so,

3x+x+10+4x-30=180

=> 8x-20=180

=> 8x=180+20=200

=> x=200 /8=25

so the angles are 3.25°=75°

(25+10)°=35°

(4.25-30)°=(100-30)°=70°

smallest angle of the triangle is 35°

Answer 2

Given :

• First angle of triangle 3x°
• Second angle of triangle (x + 10)°
• Third angle of triangle (4x - 30)°

To find :

• Smallest angle of triangle

According to the question,

As we know that,

Sum of all angles of a triangle is 180°

→ 3x + x + 10 + 4x - 30 = 180°

→ 8x - 20 = 180°

→ 8x = 180° + 20°

→ 8x = 200°

→ x = 200° ÷ 8

→ x = 25°

★ Value of 3x :

→ 3x

→ 3(25°)

→ 75°

★ Value of x + 10 :

→ x + 10

→ 25° + 10°

→ 35°

★ Value of 4x - 30 :

→ 4x - 30

→ 4(25°) - 30

→ 100° - 30°

→ 70°

So, the smallest angle is 35°.
