Question

The measure of three angles of triangle are 3x-17, x+40, 2x-5. Find x and

each angle.​

Answer 1

Step-by-step explanation:

3x-17+X+40+2x-5=180

6x-22+40. =180

6x+18. =180

6x. =180-18

6x. =162

X. =162/6

X. =27

Answer 2

Answer:

angle sum property of triangle is 180⁰

3x - 17 + x + 40 + 2x - 5 = 180⁰

6x + 18 = 180⁰

6x = 180⁰-18⁰

6x = 162⁰

x = 27⁰

angles are 3x-17 = 3×27-17 = 64⁰

x+40 = 27+40 = 67⁰

2x-5 = 2×27-5 = 49⁰
