Question

please solve this for me, thank you​

Answer 1

Since it's a triangle the sum of the Angles will be 180°

therefore,

(x+15)+(3x)+(x) = 180

5x+15 = 180

5x = 180-15

5x = 165

$x = \frac{165}{5}$

x = 33

VERIFICATION:

(x+15)+(3x)+(x)

(33+15)+(3×33)+33

48+99+33 = 180

LHS = RHS

hence verified

hope it helps

have a great day
