Question

prove thst sum of three angles of triangle is using this result find value of x and three of triangle is given that three angles of triangle are (2x-7) (x+25) (3x+12)​

Answer 1

Answer:

sum of all angles of a triangle=180

(2x-7)+(X+25)+(3x+12)=180

6x+30=180

6x=150

x=150/6

=25

so first angle is 2x-7=43

second is x+25=50

third is 3x+12=25*3+12

=75+12=87 degrees......

hope it will be helpful...
