Abcd is a square. abe is an equilateral triangle. x =

105 degrees.

Step-by-step explanation:

Given information: ABCD is a square. ABE is an equilateral.

To find : The value of x.

We know that the measure of each interior angle of a square is 90 degrees and the measure of each interior angle of an equilateral triangle is 60 degrees.

Diagonals of a square divide the interior angles in two equal parts.

We know that sum of interior angles of a triangle is 180 degrees.

Therefore, the value of x is 105 degrees.

hopefully im right

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
