Question

find the value of x in each triangle​

Answer 1

Answer:

4) x = 32°

5) x = 10 °

6) x = 3°

Answer 2

3). 1 +2 + 3 = 180⁰. ( angle sum property)

45 + 90 + (8x+21)⁰ = 180⁰

135 + (8x +21)⁰ = 180⁰

(8x+21)⁰ = 45⁰

8x. = 24

x. = 3

2).1 + 2 + 3 = 180⁰

71⁰ + 50⁰ + 6x - 1 = 180⁰

6x + 120 = 180⁰

6x = 60⁰

x = 10⁰

3).1 + 2.+ 3=180⁰

46⁰+36⁰+2-3x⁰ = 180⁰

84⁰ - 3x = 180⁰

-3x = -96⁰

x. = 32⁰
