Question

The angles of a triangle are (2x), (3x + 5) and (4x – 14)º.
Find the value of x and the measure of each angle of the triangle.​

Answer 1

Answer:

x = 21⁰

Step-by-step explanation:

We know that sum of all angle triangle = 180⁰

Thus, given that 2x + 3x + 5 + 4x - 14 = 180⁰

=> 9x = 189⁰

=> x = 21⁰

Hence, the value of x = 21⁰

Answer 2

Answer:

as the sum of the three angles of a triangle is 180° so

2x+3x+5+4x-14=180

=> 9x-9=180

=> 9x=180+9

=> 9x=189

=> x=189/9

=> x=21

so the value of x =21

angles of the triangle is 2×21°=42° ,( 3×21+5)°

=(63+5)°=68° and (4×21-14)°=(84-14)°=70°
