Pls help and show workings

x = 30

Step-by-step explanation:

Since RQ bisects ∠ PRS, then

∠ SRQ = ∠ PRQ , substitute values

3x - 20 = x + 40 ( subtract x from both sides )

2x - 20 = 40 ( add 20 to both sides )

2x = 60 ( divide both sides by 2 )

x = 30

11

Step-by-step explanation:

Let x be the unknown number

2x+5 = 27

Subtract 5 from each side

2x+5-5 = 27-5

2x = 22

Divide each side by 2

2x/2 = 22/2

x = 11

The number is 11
