Question

in the given figure find x ( 2x + 15 ) ( x + 10 ) (3x + 5 ) be fast I will mark you as BRANILIEST ​

Answer 1

Answer:

x = 25

Step-by-step explanation:

2x + 15 + x + 10 + 3x + 5 = 180 (Angle Sum Property)

6x + 30 = 180

6x = 150

x = 25

Answer 2

Given :- In ∆ABC ,

• ∠A = (x + 10)°
• ∠B = (3x + 5)°
• ∠C = (2x + 15)°

To Find :- Value of x .

Concept used :-

• Angle sum property of a triangle :- Sum of all three angles of a triangle is equal to 180° .

Solution :-

→ ∠A + ∠B + ∠C = 180° { By angle sum property. }

putting given values,

→ (x + 10)° + (3x + 5)° + (2x + 15)° = 180°

→ x + 3x + 2x + 10° + 5° + 15° = 180°

→ 6x + 30° = 180°

→ 6x = 180° - 30°

→ 6x = 150°

→ 6x = 6° × 25°

dividing both sides by 6,

→ x = 25° (Ans.)

Hence, value of x is equal to 25° .
