Question

if angles of a traingle are (x-10), (2x+10) and 6x then the value of x is
​

Answer 1

Answer:

x=20

Step-by-step explanation:

Sum of all angles of triangle is 180

x+2x+6x+10-10=180

9x=180

x=20

Answer 2

Answer:

(X-10) + (2x +10) + (6x) = 180 ( sum of all angles of triangle)

10x -0 = 180

X = 180/10

X = 18

So, first angle is ( 18 - 10) = 8

And second angle is (2(18) + 10) = 46

6 x 13 = 78
