Question

∆P=45 ∆Q=(3x+16) ∆R=68°

Answer 1

45+3x+16+68=180
=> 3x+61+68=180
=> 3x+129=180
=> 3x= 51
=> x = 17


Hence, angle Q = 3(17)+16=51+16=67°

Answer 2

Hey mate,

Here is ur answer,

P= 45 , Q =3x+16 , R =68.

By Angle sum property.

P+Q+R =180.

=> 45+3x+16+68 =180

=> 3x+119 =180.

=> 3x=180-129 = 51.

=> x=51/3 =17.

Q =3(17) +16.

=> 51+16.

=> 67.
