DB should equal CB plus DC.

First write an expression to represent DC.
(x+168)-(3x+134)
x+168-3x-134
-2x+34

Then write an equal for DC plus CB equals DB
-2x+34+71= 153+2x
-2x+105= 153+2x
-4x+105=153
-4x=48
x= -12

Now plug in the value of x to find DB
153+2(-12)
153-24
129

Final answer: 129

natka813 [3]

<h2>Given :-</h2>

In □PQRS side PQ∥ side RS. If m∠P = 108degree

and m∠R = 53degree

<h2>To Find :-</h2>

m∠Q and m∠S.

<h2>Solution :-</h2>

According to angle sum property

P∠Q=180−∠P

∠Q=180−108

\boxed{\sf{\angle Q = 72°}}

For angle S

∠S=180−∠R

∠S=180−53

\boxed{\sf {\angle S = 127°}}
