1. (x+10)+26=90°

(x) + 36 = 90

(x) = 90 – 36

(x) = 54°

< ADB = 10 + 54 = 64°

2. (x-13) + 59 =90°

(x )+ 46 = 90

(x) = 90 – 46

(x) = 44°

< PSQ = (x-13)

= (44 – 13)

= 31°

3. (2x + 3) + 73 = 180°

(2x) + 76 = 180

(2x) = 180 – 76

(2x) = 104

(x) = 104/2

(x) = 52°

< DBC = 2x + 3

= 2(52) + 3

= 104 + 3

= 107°

4. (x-28) = 149

(x) = 149 + 28

(x) = 177°

< SOV = 180 – 149

= 31°
