Question

In the given digram find 'x'

Answer 1

By angle sum property
<QPR+<PRQ+<PQR = 180
45+68+(3x+16)=180

OPEN THE BRACKET
45+68+3x+16=180
129+3x=180
3x=180-129
3x=51
x=51/3
x=17

Answer 2

Hey...!! Here Is Your Ans...

Sum Of All Angle Of Triangle = 180°

Therefore,
45 + 68 + 3x + 16 = 180

129 + 3x = 180

3x = 180 - 129

3x = 51

x = 51\3

x = 17
