Angle BDA is 90°

$(2x + 3) + 55 = 90 \\ 2x + 3 + 55 = 90 \\ 2x + 58 = 90 \\ 2x = 90 - 58 \\ 2x = 32 \\ x = \frac{32}{2} \\ \boxed{x = 16}$

Hence,

x=16Angle BDA is 90°.

(7, 3.5)

Step-by-step explanation:

find the distances between the x and y

9 and 5 are 4 apart, and 2 and 5 are 3 apart

divide those distances by 2

4/2 = 2, 3/2 = 1.5

add those distances to the smaller of the x and y

5 + 2 = 7, 2 + 1.5 = 3.5

those two numbers are the midpoint (7, 3.5)
