So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.

$120+100+120+x+10+120+x=720$

Combine like terms to get $2x+470=720$

Subtract 470 on each side to get $2x=250$

Then just divide on each side and you'll get $x=125$

To find the value of the (x+10) angle, just substitute 125 for x and solve.

$125+10=135$

Answer:

Hence, a carpenter can paint a maximum of 7 chairs.

Hence, option A is correct.

Step-by-step explanation:

A carpenter has less than 120 min. to spend painting furniture each day.

Today, he has spent 30.5 min. painting a desk.

Now he will paint x chairs, each of which takes 12.5 min.

i.e. he will take a total of 12.5x minutes in painting 'x' chairs.

Also total time spent on painting furniture each day will be equal to time spent on painting a desk and all of the chairs.

Hence,

30.5+12.5x<120 (since the total time he spends on painting is less than 120 mins.)

⇒ 12.5 x<120-30.5

⇒ 12.5 x<89.5

⇒ x<7.16 ( on dividing both side of the inequality with 12.5)

Hence, a carpenter can paint a maximum of 7 chairs.
