Question

The measures of the angles of the triangle solve for x

Answer 1

Answer:

x = 8

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

3x + 12 + 54 + 90 = 180, simplify

3x + 156 = 180 ( subtract 156 from both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Answer 2

Answer:

x = 8

Step-by-step explanation:

if the angle is equal to 36º that means (3x+12)º = 36º so simplify the equation and solve for x

3x+12 = 36

3x = 24

x = 8
