Answer:
The answer are
- 60⁰
- 97⁰
- 46.78⁰
Step-by-step explanation:
In terms of question no.1,
2x + x + x + 2x = 360⁰
or,6x=360⁰
or,x=360⁰/6
HENCE x = 60⁰##
In terms of question no.2,
( x + 10 )⁰ + x + x +59⁰ = 360⁰
or, 3x + 69⁰ = 360⁰
or, 3x = 360⁰ - 69⁰
or, x = 291⁰/3
HENCE x = 97⁰##
In terms of question no. 3,
(4x + 6)⁰+ 5x + 113⁰ + 90⁰ = 540⁰
or,9x + 119⁰ = 540⁰
or,9x = 540⁰ - 119⁰
or,x = 421/9
HENCE x = 46.78⁰
