Question

This one dont make sense

Answer 1

Answer: x=6

Explanation:

90-75=15

15-3=12

12/2=6

the little box means 90 degree angle

Answer 2

x = 6

Explanation:

Complementary angles:

If sum of two angles add up to 90°, they are called complementary angles.

75 + 2x +3 = 90

2x + 78 = 90

Subtract 78 from both sides,

2x = 90 - 78

2x = 12

Divide both sides by 2

x = 12÷2

x = 6°

2x + 3 = 2*6 + 3

= 12 + 3

= 15°
