The sum of the interior angles in a triangle is 180 degrees. Therefore, if we add up all of these angles, they must be equal to 180.

64 + 85 + (4x + 27) = 180

176 + 4x = 180

4x = 4

x = 1

Let's check our answer!

4(1) + 27 = 31

31 + 85 + 64 = 180

180 = 180

Hope this helps!! :)

Answer:

x=1

Step-by-step explanation:

The sum of the angles in a triangle is 180

64+ 85+ 4x+27 = 180

Combine like terms

4x+176=180

Subtract 176 from each side

4x+176-176 =180-176

4x = 4

Divide by 4

4x/4 = 4/4

x=1
