Answer:

C = 38, x = 50

Step-by-step explanation:

4. All the angles must be equal to 180.

Hence.

3c + 2c - 10 =180

5c - 10= 180

5c = 190

C = 38

5. First solve for angle c = 360- 330 = 30

The internal angles of a triangle is 180.

Hence.

x + 2x + 30 = 180

3x = 150

x = 50

For #4 - c=38

38x3=114 and 38x2-10=66. 114+66=180

For #5 - x=50

180=30+3x

(subtract 30 from both)

150=3x

(divide by 3)

50=x
