Answer:

Step-by-step explanation:

the sum of the internal angles of a triangle is 180 °, subtract from 180 ° the value of the known angles and you will have the value of 2x-5.

then solve with an equation.

180 - 20 - 50 = 110

then

2x - 5 = 110

2x = 110 + 5

2x = 115

x = 115 : 2

x = 57.5

----------------------------

2 * 57.5 + 50 + 20 =

115 + 50 + 20 = 185

(-5) - 4(.5) = -7

-5 - 2 = -7

-7 = -7
