Answer 1

Answer:

1)

5x+x+90⁰=180⁰

6x=180⁰-90⁰

6x=90⁰

x=90/6

x=15⁰

2)(5y+3)+(4y+8)+34⁰=180⁰. -----(180⁰-146⁰=34⁰)

=9y+11+34=180⁰

=9y+45=180⁰

=9y=180⁰-45⁰

9y=135⁰

y=135⁰/9

y=15⁰

please Mark me as brainliest

Answer 2

Answer:

a). 90+5x+x=180

90+6x=180

6x=180-90

6x=90

x=90/6

x=15

Step-by-step explanation:

b). 146+(4y+8)+(5y+3)=180

146+4y+8+5y+3=180

146+8+3+4y+5y=180

159+9y=180

9y=180-159

9y=21

y=21/9

y= 7/3
