Question

Answer the question please

Answer 1

x = 45

Explanation:

1. The sum of the interior angles of any quadrilateral is 360°
2. so 2x+2x+30+2x-10+x+25 = 360°

we solve the equation

2x+2x+30+2x-10+x+25 = 360

7x = 360 - 30 + 10 - 25

7x = 315

x = 315 : 7

x = 45

Answer 2

x = 45°

Explanation:

Quadrilaterals:

Sum of all the angles of quadrilateral = 360

2x + 2x + 30 + 2x - 10 + x + 25 = 360

2x + 2x + 2x + x + 30 - 10 + 25 = 360

Combine like terms,

7x + 45 = 360

Subtract 45 from both sides,

7x = 360 - 45

7x = 315

Divide both sides by 7,

x = 315 ÷ 7

`\boxed{\bf x = 45^\circ}`
