Having trouble to find the answer pls

it is 20

Step-by-step explanation:

5 * 20 = 100

100 - 10 = 90 which equals a angle in a right angle triangle

The value of x is 11 ⇒ answer B

Step-by-step explanation:

* lets check the properties of the square

- Its four aides are equal

- Its four angles are equal and the measure of each one is 90°

- Its diagonals bisect its vertices

∵ BD is a diagonal of the square

∴ BD bisects angle B

∴ m∠ABD = m∠CBD

∵ B is a vertex of the square

∴ m∠B = 90°

∴ m∠ABD = m∠CBD = 90 ÷ 2 = 45°

∵ m∠ABD = (5x - 10)°

∴ (5x - 10)° = 45° ⇒ add 10 to each side

∴ 5x = 55 ⇒ divide both sides by 5

∴ x = 11

* The value of x is 11
