The 3 angles in a triangle sum up to 180° (Angle sum property of a triangle).

90° + 36° + (7x + 5)° = 180°

126 + 7x + 5 = 180

131 + 7x = 180

7x = 180 - 131

7x = 49

x = 49/7

x = 7

Answer:

x=7

Step-by-step explanation:

The sum of the angles of a triangle are 180

90+36+ 7x+5 = 180

131+7x = 180

7x = 180-131

7x =49

Divide by 7

7x/7 = 49/7

x=7
