Question

Solve for the nearest tenth *

Answer 1

Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

x = (65)

• 20 + 55 + 40 = 115
• 180 - 115 = 65
• Therefore, x = 65

Answer 2

Answer:

x = 65.

Step-by-step explanation:

= 20 + 55 + 40

= 115

= 180 - 115 = 65.
