Answer:

∠ DBE = 25.5°

Step-by-step explanation:

Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then

∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°

Find the value of x.

alukav5142 [94]

Step-by-step explanation:

The sum of the three angles in a triangle must be $180$ . Since this triangle has a right angle, we know that it is $90$ °, so the sum of the remaining two angles must be $90$ .

We can set up an equation for the two remaining angles to determine the value of $x$ :

$(x + 28) + x = 90$

$2x + 28 = 90$

$2x = 62$

$x = 31$
