Answer:

20

Step-by-step explanation:

Straight line angles:

     Angles on a straight line add up to 180°.

 90 + 4x - 10 + x = 180

 90 - 10 + 4x + x = 180

Combine like terms.

         80 + 5x     = 180

Subtract 80 from both sides,

                 5x    = 180 - 80

                    5x = 100

Divide both sides by 5

                      x = 100 ÷ 5

                      \sf \boxed{x = 20^\circ}

lianna [129]

Given:

Yamir is twice as old as Pato.

In three years, the sum of their ages will be 30.

Pato's current age is represented by a.

To find:

The equation that could be used to correctly solve for a.

Solution:

We know that, Pato's current age is represented by a, then

Yamir's age = 2a

After three years,

Pato's age = a+3

Yamir's age = 2a+3

In three years, the sum of their ages will be 30.

(a+3)+(2a+3)=30

(a+2a)+(3+3)=30

a+2a+6=30

Therefore, the correct option is 2.
