Question

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

Answer 1

Answer:

here,sum of angles in a triangle is 180.

equating we get,

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

9x-9=180

9x=189

x=21

there fore angles are

2x= 2 x 21  =  42°

3x+5=3(21)+5= 68°

4x-14=4(21)-14=  70°      ( here you can see that 42 +68 +70=180)

hope it helps.....

Answer 2

$\huge\mathcal\pink{\underline{\underline{♡Añswer♡}}}$

➡️ (2x) + ( 3x + 5) + ( 4x - 14 ) = 180

➡️ 2x + 3x + 5 + 4x - 14 = 180

➡️ 9 x + ( - 9 ) = 180

➡️ 9 x - 9 = 180

➡️ 9x = 180 + 9

➡️ 9x = 189

➡️ x = 189 / 9

so , x = 21

SO THE VALUE OF X = 21
